Some of us think only accidents happen to those who take part in risky behavior or are on the more adventurous side, but the truth is an accident can occur anywhere at any time. Besides choking, internal and external severe bleeding are some of the most common emergencies we experience and are unaccustomed to handling unless we have proper First Aid training and a first aid kit at hand.

Continue readingThe three primary diabetic emergencies are hypoglycemia (low blood sugar), diabetic ketoacidosis (DKA), and hyperosmolar hyperglycemic state (HHS). For a conscious person with low blood sugar, give 15 grams of fast-acting sugar and wait 15 minutes. That is the Rule of 15. For DKA or HHS, call 911 immediately and do not give food or drink if the person is vomiting or unconscious. If the person is unconscious and carries a glucagon kit, administer it after calling 911.

Every year on November 14th, the global community observes World Diabetes Day to raise awareness about one of the fastest-growing health conditions in the world. In Canada alone, more than 3.7 million people are living with diabetes, and that number continues to rise every year. While diabetes is primarily managed through lifestyle modifications and medical treatment, the condition can produce life-threatening emergencies that require immediate attention. Diabetic emergencies are critical situations in diabetes management that require immediate attention because they can be life-threatening.
World Diabetes Day was established in 1991 by the International Diabetes Federation and the World Health Organization. November 14th was chosen because it marks the birthday of Sir Frederick Banting, the Canadian physician who co-discovered insulin in 1921 at the University of Toronto. That breakthrough has saved millions of lives and remains one of Canada’s greatest contributions to global health.
The three primary diabetic emergencies are hypoglycemia (low blood sugar), diabetic ketoacidosis (DKA), and hyperosmolar hyperglycemic state (HHS). The two most common diabetic emergencies are diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS), with severe hypoglycemia also being a key concern. Each requires a different first aid response, and each can be fatal without prompt action.
Type 1 diabetes is an autoimmune condition in which the body’s immune system attacks and destroys the insulin-producing cells in the pancreas. Without insulin, the body cannot move glucose from the bloodstream into cells for energy. People with Type 1 diabetes must take insulin every day to survive. DKA is most common in type 1 diabetes because the absolute shortage of insulin causes the body to produce ketones as an alternative fuel source. This type accounts for approximately 5 to 10 percent of all diabetes cases and is most commonly diagnosed in children and young adults.
Type 2 diabetes is the most common form, accounting for about 90 percent of all cases. It develops when the body becomes resistant to insulin or when the pancreas gradually loses its ability to produce enough insulin. HHS is more often seen in people living with type 2 diabetes, although either condition can affect anyone with diabetes. Risk factors include family history, obesity, physical inactivity, age, and ethnicity. Regular monitoring of blood glucose levels is essential for people with diabetes, especially during periods of illness, to prevent fluctuations that can lead to emergencies.
Gestational diabetes develops during pregnancy and typically resolves after birth. However, women who have had gestational diabetes have a significantly higher risk of developing Type 2 diabetes later in life. Monitoring blood glucose carefully during pregnancy is essential for the health of both mother and baby, and gestational diabetes is considered a risk factor for future hyperglycemic emergencies.
Hypoglycemia occurs when blood glucose drops below normal levels, which can starve the brain of fuel. In clinical terms, hypoglycemia is defined as blood glucose falling below 4.0 mmol/L. This is the more common and more immediately dangerous diabetic emergency in day-to-day life. It can develop rapidly within minutes and can quickly progress to unconsciousness and seizures if not treated.
Causes of hypoglycemia include taking too much insulin, skipping meals, excessive physical activity, and alcohol consumption. Certain drugs affecting blood glucose control, including medications used for infection or other conditions, can also trigger hypoglycemic episodes. People with hypoglycemia unawareness are at particular risk because they do not experience the usual warning signs before their blood glucose drops to a dangerous level, making bystander recognition even more critical.
Early signs of hypoglycemia include: shakiness and trembling, sweating and pale clammy skin, rapid heartbeat and extreme hunger, dizziness and lightheadedness, confusion and difficulty concentrating, irritability or sudden mood changes, and blurred vision and weakness.
Severe hypoglycemia can result in seizures, loss of consciousness, or coma. In Ontario, in-hospital mortality in people hospitalized for acute hyperglycemia ranged from under 1 percent at ages 20 to 49 years to 16 percent in those over 75 years, underscoring the importance of early intervention. Severe hypoglycemia requires immediate attention and emergency services if the person is unconscious, having seizures, or unable to swallow safely. The incidence of severe hypoglycemic events increases significantly in older adults and in patients with long-standing diabetes who have developed hypoglycemia unawareness.
DKA is a metabolic crisis caused by an absolute shortage of insulin, leading the body to produce ketones as an alternative fuel source. When insulin is absent, the body breaks down fat, producing ketones that acidify the blood. This process is called ketosis and, when severe, progresses to ketoacidosis. DKA is most common in people with type 1 diabetes but can affect anyone with diabetes who has severely uncontrolled blood glucose. Severe diabetic ketoacidosis is a life-threatening hyperglycemic crisis requiring emergency room treatment without delay.
In DKA, blood glucose levels are usually 14.0 mmol/L or above. Symptoms of diabetic ketoacidosis (DKA) include nausea, vomiting, abdominal pain, and a feeling of being unable to get enough oxygen, collectively referred to as acidosis. Common signs of DKA also include shortness of breath, fruity breath odor, and severe abdominal pain. Common triggers for DKA beyond missed insulin include infection, illness, cardiac surgery, and myocardial infarction, all of which dramatically increase the body’s insulin requirements. People recovering from surgery or a cardiac event should monitor blood glucose closely for signs of hyperglycemic crises.
Hyperosmolar hyperglycemic syndrome (HHS), also called hyperosmolar hyperglycemic state, hyperglycemic hyperosmolar state, or hyperosmolar nonketotic coma, is a hyperglycemic emergency that typically affects older adults with type 2 diabetes. Hyperglycemia usually develops slowly and can lead to severe dehydration and life-threatening conditions like DKA or HHS if untreated. Medications including diuretics and glucocorticoids can trigger or worsen HHS by promoting dehydration and raising blood glucose levels.
In DKA, blood glucose levels are usually 14.0 mmol/L or above, while in HHS they can be significantly higher, typically 34.0 mmol/L or above, along with plasma osmolality above 320 mOsm/kg. HHS typically presents with neurological signs such as vision problems or delirium, along with increased urination and dehydration. Signs of dehydration in HHS include extreme thirst, dry mouth, sunken eyes, and rapid pulse. HHS is a critical medical emergency requiring intensive care treatment and massive fluid rehydration as a priority. Mortality is significantly higher in HHS than in DKA, particularly in older adults and patients with pre-existing conditions.
Understanding the difference between DKA and HHS helps you communicate more clearly with emergency dispatchers and medical professionals when someone experiences a hyperglycemic crisis.
| Feature | DKA | HHS |
|---|---|---|
| Most common in | Type 1 diabetes | Type 2 diabetes |
| Blood glucose | 14.0 mmol/L or above | 34.0 mmol/L or above |
| Plasma osmolality | Normal or mildly elevated | Above 320 mOsm/kg |
| Ketones present | Yes | Minimal or absent |
| Onset | Hours to 1 day | Days to weeks |
| Breath odor | Fruity | No fruity odor |
| Neurological signs | Less common | Vision problems, delirium common |
| Dehydration | Moderate | Severe |
| Common triggers | Missed insulin, infection, cardiac surgery | Diuretics, glucocorticoids, illness |
| Treatment priority | Insulin and IV fluids | Massive fluid rehydration |
In a diabetic emergency, assessing the person’s level of consciousness and their ability to swallow safely is the most critical first step. Never give anything by mouth to someone who is unconscious or unable to swallow, as this creates a serious aspiration risk. Standard First Aid with CPR C covers diabetic emergency response, the Rule of 15, and glucagon administration as part of the core curriculum.
If blood sugar levels cannot be determined, standard protocols suggest treating as if the person has hypoglycemia. This is the safer approach because treating a high blood sugar with a small amount of sugar causes minimal harm, while failing to treat dangerously low blood sugar can be fatal.
For a conscious person who can swallow safely, follow the Rule of 15:
If the person is unconscious or unable to swallow safely, do not give anything by mouth. Call 911 immediately. Place the person in the recovery position on their side to protect their airway. If the person carries a glucagon kit and you are trained to use it, administer glucagon as directed. The glucagon kit works by signaling the liver to release stored glucose into the bloodstream, raising blood glucose without requiring oral intake. Stay with the person and monitor their breathing and level of consciousness until emergency services arrive.
Hyperglycemia that has progressed to DKA or HHS requires emergency room treatment and cannot be managed with first aid alone. Management of diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) includes restoring normal extracellular fluid volume and correcting electrolyte imbalances. Fluid therapy is essential in managing DKA, with initial intravenous normal saline administration recommended at a rate of 500 mL/h for the first four hours, followed by adjustments based on the patient’s condition.
As a bystander, your role is to call 911 immediately if the person is vomiting, has fruity-smelling breath, is breathing abnormally, or is showing signs of altered consciousness. Keep the person comfortable and calm. Place them in the recovery position if unconscious but breathing. Monitor their airway and breathing continuously. Do not give food or drink if they are vomiting or their level of consciousness is reduced. Tell paramedics what you observed, including any known diabetes diagnosis, medications, and the time symptoms began.
Hypoglycemia unawareness is a condition in which a person with diabetes no longer experiences the early warning signs of low blood glucose. Over time, the body’s hormonal response to falling blood glucose becomes blunted, particularly in people who have had diabetes for many years or who have experienced frequent hypoglycemic episodes. Blood glucose can drop to dangerous levels without the person feeling any symptoms.
For bystanders and coworkers, hypoglycemia unawareness means that someone with diabetes may appear suddenly confused, unresponsive, or unconscious without warning. This makes it especially important for people around those with diabetes to know the signs of a diabetic emergency, even when the person themselves cannot signal that something is wrong. If someone with known diabetes suddenly appears confused, pale, or unresponsive, treat for hypoglycemia immediately and call 911.
A glucagon kit is an emergency treatment for severe hypoglycemia when the person is unconscious or unable to swallow. Glucagon is a hormone that signals the liver to release stored glucose into the bloodstream. Many people with type 1 diabetes and some with type 2 diabetes carry a glucagon kit as part of their emergency preparedness.
Glucagon kits come in two forms: an injectable kit that requires reconstitution before use, and a nasal spray form that is simpler to administer. If someone collapses from a diabetic emergency and you locate a glucagon kit, call 911 first, then follow the step-by-step instructions on the kit. The correct dose is included in the kit instructions. Most modern glucagon kits are designed to be used by untrained bystanders with clear instructions. After administering glucagon, the person should begin to recover within 10 to 15 minutes. Even if they recover, paramedics should still assess them because blood glucose may drop again without follow-up treatment.
Preventing diabetic emergencies starts with proactive care, including creating a sick-day plan with healthcare providers to manage medications during illness. Illness and infection are among the most common triggers for both DKA and HHS, because physical stress causes blood glucose levels to rise even if the person is not eating. Sick-day management that includes capillary beta-hydroxybutyrate monitoring reduces emergency room visits and hospitalizations in young people with type 1 diabetes.
A comprehensive sick-day plan typically includes instructions for adjusting insulin or oral medication doses during illness, guidance on how frequently to check blood glucose when sick, rules for when to check for ketones in urine or blood, a threshold for when to call a healthcare provider or go to the emergency room, a list of safe foods and fluids to consume when unable to eat normally, and instructions for managing diuretics, glucocorticoids, and other drugs that affect blood glucose during illness. Regular monitoring of blood glucose levels is essential for people with diabetes, especially during periods when ill, to prevent fluctuations that lead to emergencies.
With 3.7 million Canadians living with diabetes, virtually every workplace has employees managing the condition. Employers have both a legal and ethical responsibility to ensure workplaces are safe and supportive for employees with diabetes. This includes allowing employees to monitor their blood sugar and take medications as needed, providing access to food and beverages for managing blood glucose, training designated first aiders to recognize and respond to diabetic emergencies, and including diabetes management in workplace emergency plans.
Investing in workplace first aid training that covers diabetic emergencies ensures that coworkers can respond effectively when someone experiences a blood sugar crisis. For workplaces with higher risk, private group first aid training can be customized to include specific diabetic emergency protocols. This training aligns with CSA Z1210:24 workplace first aid standards.
While type 1 diabetes cannot currently be prevented, the risk of developing type 2 diabetes can be significantly reduced through lifestyle modifications. Maintaining a healthy weight, engaging in at least 150 minutes of moderate physical activity per week, eating a balanced diet, limiting consumption of processed foods and sugary drinks, and getting regular health screenings are all proven strategies. The American Diabetes Association recommends a combination of aerobic exercise and resistance training for optimal glycemic control.
Physical activities like swimming are particularly beneficial for diabetes prevention and management because they provide excellent cardiovascular exercise while being gentle on the joints. Regular physical activity improves insulin sensitivity, helps maintain a healthy weight, and reduces stress, all of which contribute to better blood sugar control and overall health.
This World Diabetes Day, consider taking action by learning the signs and symptoms of diabetic emergencies, talking to friends and family members with diabetes about their emergency action plans, ensuring your workplace has trained first aiders, and enrolling in a first aid course that covers medical emergencies including diabetes.
Basic Emergency First Aid covers the fundamentals of recognizing and responding to blood glucose crises. Standard First Aid courses go deeper, covering the Rule of 15, glucagon administration, recognition of DKA and HHS, and when to call 911. Hands-on training builds the confidence and competence to act correctly under pressure when every minute matters.
Key Takeaway
The three primary diabetic emergencies are hypoglycemia, DKA, and HHS. For a conscious person with low blood sugar, use the Rule of 15: give 15 grams of fast-acting sugar and wait 15 minutes. For DKA or HHS, call 911 immediately. Never give food or drink to someone who is unconscious. If a glucagon kit is available and the person is unconscious, call 911 first then administer glucagon. Hands-on first aid training prepares you to respond with confidence to any diabetic emergency.
Learn to recognize and respond to diabetic emergencies, cardiac events, and more with a Canadian Red Cross First Aid course from Coast2Coast First Aid and Aquatics.
A: The three primary diabetic emergencies are hypoglycemia (low blood glucose), diabetic ketoacidosis (DKA), and hyperosmolar hyperglycemic state (HHS). The two most common diabetic emergencies are DKA and HHS, with severe hypoglycemia also being a key concern. Each requires a different response. Hypoglycemia is treated with fast-acting sugar for conscious patients. DKA and HHS require emergency room treatment and cannot be managed with first aid alone. In all three cases, calling 911 and monitoring the person’s airway are the most critical bystander actions.
A: The Rule of 15 is the standard first aid protocol for conscious hypoglycemia. Give the person 15 grams of fast-acting sugar such as 4 glucose tablets, half a cup of juice, or 1 tablespoon of honey. Wait 15 minutes and reassess. If symptoms have not improved, repeat the dose. Once symptoms resolve, give a more substantial snack to stabilize blood glucose levels. This protocol is covered in Standard First Aid and CPR certification courses.
A: Do not give anything by mouth. Call 911 immediately. Place the person in the recovery position on their side to protect their airway. If they carry a glucagon kit and you are trained to use it, administer glucagon as directed. The glucagon signals the liver to release stored glucose into the bloodstream. Monitor their breathing and level of consciousness continuously until paramedics arrive. Severe hypoglycemia can result in seizures, loss of consciousness, or coma, so acting quickly is essential.
A: Both are hyperglycemic crises but differ in key ways. In DKA, blood glucose is typically 14.0 mmol/L or above and ketones are present, producing fruity breath and acidosis. In HHS, blood glucose is significantly higher at 34.0 mmol/L or above, along with plasma osmolality above 320 mOsm/kg. Ketones are minimal or absent in HHS. DKA is most common in type 1 diabetes and develops over hours. HHS typically affects older adults with type 2 diabetes, develops over days to weeks, and presents with severe dehydration and neurological signs. HHS requires massive fluid rehydration as a priority.
A: Call 911 immediately if the person is unconscious or unresponsive, having seizures, unable to swallow, vomiting, breathing abnormally, showing signs of severe dehydration, or has fruity-smelling breath indicating possible DKA. Also call 911 if they do not improve after two rounds of the Rule of 15, or if you are unsure of the cause of their altered consciousness. Diabetic emergencies are critical situations in diabetes management that require immediate attention.
A: Hypoglycemia unawareness is a condition in which a person with diabetes no longer experiences the early warning signs of low blood glucose. Blood glucose can drop to dangerous levels without the person feeling any symptoms. This makes bystander recognition critical. If someone with known diabetes suddenly appears confused, pale, or unresponsive without warning, treat for hypoglycemia immediately and call 911. People with hypoglycemia unawareness are at significantly higher risk of severe hypoglycemic episodes.
A: A glucagon kit is an emergency treatment for severe hypoglycemia in unconscious patients. Glucagon signals the liver to release stored glucose into the bloodstream, raising blood glucose without requiring the person to eat or drink. Many people with type 1 diabetes carry a glucagon kit as part of their emergency preparedness. Glucagon kits are available as injectable preparations or nasal sprays. Call 911 first, then administer glucagon according to the kit instructions at the correct dose. Even if the person recovers after glucagon, they still need paramedic assessment.
A: DKA is a metabolic crisis caused by an absolute shortage of insulin, leading the body to produce ketones. Common triggers include missed insulin doses, illness or infection, cardiac surgery, and myocardial infarction. DKA symptoms include nausea, vomiting, abdominal pain, fruity breath, and deep rapid breathing. Treatment requires hospital care including fluid therapy, with initial intravenous normal saline at 500 mL/h for the first four hours, along with insulin and electrolyte correction. As a bystander, call 911 and monitor the person’s airway until help arrives.
A: Hyperosmolar hyperglycemic syndrome (HHS), also called hyperglycemic hyperosmolar state or hyperosmolar nonketotic coma, is a life-threatening hyperglycemic emergency most common in older adults with type 2 diabetes. Blood glucose rises to 34.0 mmol/L or above, and severe dehydration causes plasma osmolality to exceed 320 mOsm/kg. HHS typically presents with neurological signs such as vision problems or delirium, along with increased urination and extreme thirst. HHS is a critical medical emergency requiring intensive care treatment and massive fluid rehydration as a priority.
A: A sick-day plan is a personalized protocol created with a healthcare provider that guides a person with diabetes through managing their condition during illness. It includes instructions for adjusting medications including diuretics and glucocorticoids, monitoring blood glucose more frequently, checking for ketones in urine, and knowing when to seek emergency care. Preventing diabetic emergencies starts with proactive care, including creating a sick-day plan. Sick-day management that includes capillary beta-hydroxybutyrate monitoring reduces emergency room visits and hospitalizations in young people.
A: Give 15 grams of fast-acting sugar. Options include 4 glucose tablets, half a cup of fruit juice or regular soft drink, 1 tablespoon of honey or sugar, or 6 to 7 hard candies. Only give food or drink if the person is conscious and able to swallow safely. If blood sugar levels cannot be determined, standard protocols suggest treating as if the person has hypoglycemia. After symptoms improve, follow with a snack containing carbohydrates and protein to stabilize blood glucose.
A: Common signs of DKA include shortness of breath, fruity breath odor, nausea, vomiting, and severe abdominal pain. Symptoms of diabetic ketoacidosis include a feeling of being unable to get enough oxygen, referred to as acidosis. Blood glucose in DKA is typically 14.0 mmol/L or above, and ketones will be present in urine. The person may also show confusion, drowsiness, and eventual loss of consciousness or coma. DKA symptoms develop over hours to a day, unlike hypoglycemia which can develop within minutes.
A: Yes. With 3.7 million Canadians living with diabetes, virtually every workplace has employees managing the condition. Diabetic emergencies can occur at any time, including during high-exertion work, periods of illness, or when meals are delayed. Employers are legally and ethically responsible for ensuring workplaces have trained first aiders who can recognize and respond to blood glucose crises. Private group first aid training can be tailored to include diabetic emergency protocols specific to your workplace.
A: Hypoglycemia is low blood glucose, defined as blood glucose falling below 4.0 mmol/L, which can starve the brain of fuel. Early signs include shakiness, sweating, pale and clammy skin, rapid heartbeat, and extreme hunger. Hyperglycemia is high blood glucose in a hyperglycemic state, typically above 11.0 mmol/L, which develops slowly and can progress to DKA or HHS if untreated. If unsure which condition a person is experiencing, treat for hypoglycemia first, as this is the more immediately dangerous condition.

An Emergency Medical Responder (EMR) course is an advanced pre-hospital care training program that prepares individuals to provide immediate life-saving medical assistance in emergency situations. Unlike standard first aid or CPR/AED courses, EMR training goes significantly deeper into patient assessment, trauma management, medical emergencies, and the use of specialized equipment. EMR-certified individuals serve as the critical bridge between the moment an emergency occurs and the arrival of paramedics or hospital-based care, making this certification invaluable for anyone working in high-risk environments or pursuing a career in emergency services.
In Canada, the EMR certification program is designed to meet the standards set by provincial regulatory bodies and is recognized nationally as a foundational credential in the emergency medical services profession. Whether you are a firefighter, lifeguard, security professional, remote worker, or someone considering a career in paramedicine, EMR training provides the knowledge and skills to manage complex medical emergencies with competence and confidence.
While EMR certification is valuable for virtually anyone, certain groups benefit particularly from this advanced level of training:
For individuals pursuing a career in paramedicine, nursing, or emergency medicine, EMR certification serves as an essential stepping stone. Many paramedic programs across Canada either require or strongly recommend EMR certification as a prerequisite for admission. The course provides a solid foundation in patient care principles, medical terminology, and clinical skills that prepare students for the more advanced training that follows in paramedic college programs.
First responders such as firefighters and police officers are frequently the first to arrive at emergency scenes. EMR training equips these professionals with the medical knowledge to assess patients, manage injuries, and provide stabilizing care while waiting for ambulance services. Many fire departments and police services across Canada require or encourage their members to hold EMR certification.
Workers in mining, oil and gas, forestry, construction, and other industrial sectors often operate in remote locations where ambulance response times may be 30 minutes or longer. For these workers, EMR-level training can be the difference between life and death, as they may need to manage serious injuries and medical emergencies for extended periods before professional medical help arrives. Many employers in these industries require EMR certification as a condition of employment.
Aquatic environments present unique emergency scenarios including drowning, spinal injuries from diving accidents, and hypothermia. Lifeguards with EMR certification possess advanced assessment and management skills that complement their water rescue training, making them more effective at managing complex aquatic emergencies. BLS certification is often a companion credential for aquatic professionals alongside EMR.
An EMR course covers an extensive curriculum designed to prepare you for a wide range of medical emergencies. The training combines theoretical classroom instruction with hands-on practical skills sessions and realistic emergency simulations. Here is an overview of the major topics covered:
Enrolling in an Emergency Medical Responder course transitions a student from basic first aid to advanced clinical intervention. The primary objective of an Emergency Medical Responder course is to master the “Primary Survey,” where you learn to identify and treat life-threatening issues with the airway, breathing, and circulation (ABCs) in seconds. Throughout an Emergency Medical Responder course, you will move beyond simple bandages to utilizing specialized equipment like manual suction units, oxygen cylinders, and cervical collars. By the end of an Emergency Medical Responder course, participants are capable of leading a medical team during multi-system trauma events, ensuring that high-level care is maintained until a paramedic transport unit arrives.
The cornerstone of EMR training is learning how to systematically assess a patient. You will learn to perform primary surveys to identify and address immediately life-threatening conditions, followed by secondary surveys that involve a thorough head-to-toe physical examination. You will also learn to obtain a patient history using standardized questioning techniques, take vital signs including blood pressure, pulse, respiratory rate, and oxygen saturation, and document your findings accurately for handover to paramedics.
Managing a patient’s airway is the single most critical skill in emergency medicine. EMR training covers advanced airway management techniques including the use of oropharyngeal and nasopharyngeal airways, suctioning equipment, and supplemental oxygen delivery systems. You will learn to recognize and manage airway obstructions, perform advanced rescue breathing techniques, and use bag-valve-mask (BVM) devices for assisted ventilation.
Traumatic injuries — from motor vehicle accidents, falls, workplace incidents, and other causes — require specialized knowledge to manage effectively. The EMR course covers wound care, splinting and immobilization of fractures and dislocations, spinal motion restriction techniques, management of chest and abdominal injuries, burn treatment, and multi-system trauma assessment. You will learn to rapidly identify the most serious injuries and prioritize treatment accordingly.
Beyond trauma, EMR students learn to recognize and manage a wide range of medical conditions including cardiac emergencies, stroke, diabetic emergencies, seizures, respiratory distress, allergic reactions and anaphylaxis, poisoning, and environmental emergencies such as hypothermia and heat stroke. Understanding these conditions and their management is essential for providing effective pre-hospital care.
EMR training includes comprehensive CPR and AED certification at the healthcare provider level. This goes beyond basic CPR to include two-rescuer CPR techniques, advanced airway management during resuscitation, and the integration of AED use into a coordinated resuscitation effort. You will practice these skills extensively to develop the muscle memory needed to perform them effectively under the stress of a real cardiac arrest.
The EMR course is significantly more comprehensive than standard first aid training. Depending on the training provider and delivery format, the course typically ranges from 40 to 80 hours of instruction. This includes classroom lectures covering medical theory and protocols, hands-on skills labs where you practice techniques on mannequins and simulated patients, scenario-based training using realistic emergency simulations, and written and practical examinations to assess your competence.
Some training providers offer intensive formats that condense the course into consecutive days, while others spread the training over several weekends to accommodate working professionals. Blended learning options may also be available, allowing you to complete theoretical components online before attending in-person practical sessions. Regardless of the format, the practical skills component requires in-person attendance, as hands-on practice is essential for developing the competence needed to perform these skills in real emergencies.
To earn your EMR certification, you must successfully complete all course components and pass both written and practical examinations. The written exam tests your theoretical knowledge of anatomy, physiology, pathophysiology, and treatment protocols. The practical exam evaluates your ability to perform patient assessments and manage simulated emergency scenarios under timed conditions. Most provinces require a minimum passing grade of 70 to 75 percent on both components.
EMR certification is typically valid for three years, after which you must complete a recertification course to maintain your credentials. Recertification ensures that your skills remain current and that you are updated on any changes to treatment protocols or best practices. Staying current with your certification demonstrates professionalism and commitment to providing the highest standard of emergency care.
EMR certification opens doors to a variety of career paths in emergency services and beyond. Certified EMRs work in fire departments, industrial sites, event management companies, private ambulance services, remote medical facilities, security firms, and outdoor recreation organizations. The certification also serves as a competitive advantage for lifeguards, security professionals, and fitness instructors who want to differentiate themselves in the job market.
For those pursuing paramedicine as a career, EMR certification provides invaluable practical experience that strengthens paramedic school applications and prepares students for the academic rigour of advanced emergency medical training. Many successful paramedics credit their EMR training as the foundation that gave them the confidence and clinical thinking skills needed to excel in their careers.
Executive Summary: An Emergency Medical Responder (EMR) course provides the advanced clinical skills necessary to manage complex trauma and medical crises. Far exceeding Basic or Intermediate First Aid, this 80-hour program aligns with 2026 CSA Z1210:24 standards for high-risk workplace responders. Whether you are preparing for a career in paramedicine or securing a remote industrial site, EMR certification ensures you can provide emergency room level assessment and stabilization in the field.

Emergency first aid help in a mass casualty or trauma event starts with the Check, Call, Care framework: check the scene is safe, call 911, then care for the injured. The most critical skill is severe bleeding control using direct pressure, wound packing, or tourniquet application. A person can bleed to death in 3 to 5 minutes. Begin CPR immediately if the person has no pulse and is not breathing. First aid certification is valid for three years in Canada under CSA Z1210:24 standards.
Canadian Red Cross Emergency First Aid, Standard First Aid, and EMR courses covering trauma response, bleeding control, CPR, and AED use across Canada.
First aid is the immediate care given to someone who is ill or injured, involving simple, life-saving techniques that can be performed by anyone, from lay responders to medical professionals. In a mass casualty event or serious trauma emergency, knowing how to provide emergency first aid help in the minutes before emergency medical services arrive can be the difference between life and death. Everyone should know essential first aid techniques like CPR, the Heimlich maneuver, and severe bleeding control, as they can save a life before professional medical help arrives.
In any mass casualty event, emergency medical services face extraordinary challenges. The sheer number of victims, the need to secure the scene, and the logistical complexity of deploying multiple ambulances all contribute to delayed medical care. The standard protocol for responding to a medical emergency follows the Check, Call, Care framework: check the scene for safety, call emergency services, and provide care to the injured person. First aid training equips individuals with the knowledge, practice, and confidence to respond effectively to common medical emergencies until professional help arrives.
The concept of the Platinum Ten Minutes, the first ten minutes after a traumatic injury, highlights how critical immediate intervention is. Hemorrhage, or severe bleeding, is the number one cause of preventable death in trauma situations. A person can bleed to death from a major wound in as little as three to five minutes. Prompt action prevents severe blood loss and potential shock. This timeline makes it clear that waiting for paramedics is simply not an option when someone is bleeding profusely.
Before rushing to help any injured person, you must ensure your own safety. This principle is fundamental to all emergency response and is the first thing taught in every first aid course and first aid training program. In an active threat situation, seek cover immediately and do not attempt to provide first aid until the area has been secured by law enforcement or you are confident the threat has passed.
Once you have determined it is safe to act, quickly assess hazards to protect yourself and others before approaching, then call 911 immediately if it has not already been done. Provide the dispatcher with as much information as possible, including the location, the number of injured people you can see, and the types of injuries present. Use any available protective equipment, such as gloves, if it is on hand. If multiple bystanders are available, delegate the 911 call to someone specific while you begin providing basic first aid.
The single most important first aid skill in a mass casualty scenario is the ability to control severe bleeding. Shock can occur rapidly after severe trauma or heavy blood loss and is a life-threatening emergency. Apply firm, direct pressure to the wound using a clean cloth, sterile dressing, or your hands. There are several techniques depending on the location and severity of the wound.
For most wounds, applying firm, direct pressure is the first and most effective method of controlling bleeding. Use a clean cloth, clothing, or gauze and press it firmly against the wound. Do not lift the material to check if the bleeding has stopped, as this disrupts any clots that may be forming. If blood soaks through the first layer of material, add more on top without removing the original dressing. Maintain steady, firm pressure until emergency medical services arrive.
For deep wounds, particularly those in areas where a tourniquet cannot be applied such as the neck, armpit, or groin, wound packing is essential. This involves stuffing clean material directly into the wound cavity and then applying firm pressure on top. While this may seem uncomfortable for the injured person, it is a proven life-saving technique that stops internal bleeding by creating pressure from within the wound itself.
For severe bleeding from an arm or leg that cannot be controlled with direct pressure alone, a tourniquet may be necessary. A commercial tourniquet is ideal, but in an emergency, you can improvise one using a belt, tie, or strip of fabric at least 4 centimetres wide. Apply the tourniquet 5 to 7 centimetres above the wound, never directly on a joint, and tighten it until the bleeding stops. Note the time of application, as this information is critical for medical professionals. Contrary to outdated beliefs, modern medical guidance confirms that properly applied tourniquets save lives and rarely result in limb loss.
Gunshot wounds to the chest are particularly dangerous because they can cause a condition called pneumothorax, commonly known as a collapsed lung. If you see a wound on the chest that is bubbling or making a sucking sound, this is a sucking chest wound and requires immediate attention. Cover the wound with an occlusive dressing. Any non-porous material such as plastic wrap, a plastic bag, or even a credit card can work in an emergency. Seal the dressing on three sides, leaving the fourth side open to allow air to escape but preventing air from being sucked into the chest cavity. This improvised chest seal can prevent a life-threatening tension pneumothorax.
Victims of traumatic injuries frequently go into a life-threatening condition called shock, though it can also follow a sudden medical illness, where the body’s organs are not receiving enough blood flow. Signs of shock include pale or clammy skin, rapid shallow breathing, confusion, weakness, and a rapid pulse. To manage shock, keep the victim lying down with their legs elevated about 30 centimetres if possible and if their injuries allow. Cover them with a blanket or jacket to maintain body temperature. Reassure them calmly and continuously, as psychological support is an important component of shock management. Do not give them anything to eat or drink.
If an injured person has no pulse and is not breathing, begin CPR immediately. Cardiopulmonary resuscitation keeps oxygen flowing to the brain and organs when a person’s heart stops. Push hard and fast on the centre of the chest at a rate of 100 to 120 compressions per minute, allowing full chest recoil between compressions. If an AED is available, use it as soon as possible. CPR and AED certification courses typically include hands-on practice, real-life scenarios, and step-by-step instruction to ensure participants can respond effectively under pressure.
In a mass casualty event, prioritize victims with severe bleeding that can be controlled before those in cardiac arrest, as bleeding control affects a larger number of potentially survivable victims. If trained rescuers are available, delegate CPR to one person while others manage bleeding in additional victims.
Learn These Skills
Reading about bleeding control and CPR is a start. Hands-on practice is what builds the confidence to act when it matters. Canadian Red Cross Standard First Aid takes one day.
When multiple people are injured, you must quickly assess victims to determine who needs emergency treatment most urgently. This process is called triage. As a general rule, prioritize victims with severe bleeding that can be controlled, as these individuals have the best chance of survival with immediate intervention. Adults and older children who are alert and able to walk should be directed to move to a safe area. When providing emergency first aid help to multiple victims, focus efforts where they can have the greatest life-saving impact. Do not allow further harm to occur by moving victims unnecessarily unless the scene is still dangerous.
Having the right first aid equipment and supplies readily available can dramatically improve your ability to provide emergency first aid help. An emergency first aid certificate course will cover what to keep in a trauma kit. Consider carrying a compact kit that includes:
First aid kits and aid kits of this type are small enough to fit in a backpack, glove compartment, desk drawer, or car and can make the difference between effective first aid and feeling helpless in a crisis. Many first aid training providers sell or recommend specific trauma kits as part of their aid courses.
An emergency first aid course is a structured training program designed to prepare participants with life-saving techniques such as CPR, AED use, bleeding control, and emergency scene management. Most emergency first aid courses in Canada are completed in one full day, approximately 6 to 8 hours, with some providers offering blended learning formats where theory is completed online and practical skills are practised in person. Instructors teach these skills through guided practice and scenario-based instruction.
An emergency first aid certificate is an official document confirming that you have successfully completed training in first aid, CPR, and AED use, often required by employers to meet workplace safety requirements. First aid certification typically remains valid for three years, after which recertification is required to maintain compliance with workplace and safety standards.
For those who want deeper practical skills, advanced first aid training such as the Emergency Medical Responder (EMR) program provides in-depth trauma management including advanced bleeding control, spinal immobilization, and patient assessment. EMR certification represents the gold standard of pre-hospital emergency care training.
In Canada, the federal government announced the standardization of workplace first aid training in 2012, with new standards developed by the Canadian Standards Association (CSA) rolling out in 2024 to ensure consistency and quality in first aid training across the country. CSA Z1210:24 establishes standardized training requirements that affect recertification processes across all provinces and territories.
Employers in Canada are legally required to ensure that a certain number of trained first aiders are present in every workplace, with requirements varying by province, industry, and workplace size. Recertification courses often include updated training on new techniques and standards to ensure that participants are aware of the latest practices in first aid. Workplaces that handle chemicals, operate in remote locations, or expose workers to significant physical risk typically require Standard or Intermediate First Aid rather than the basic level. People who work with children may also need a course level or certification that matches their workplace requirements and responsibilities. For workplaces that want to train multiple employees at once, private group first aid training can be arranged on-site.
While this article provides an overview of critical techniques, reading about emergency first aid help is no substitute for hands-on training that prepares people to handle unexpected emergencies. In a high-stress emergency, trained individuals perform significantly better than those without training because muscle memory and practised skills take over when the mind is overwhelmed. Comprehensive first aid courses cover these techniques in detail, providing realistic practice scenarios that build both competence and confidence.
Standard First Aid with CPR C covers emergency bleeding control, shock management, chest injuries, CPR, and AED use as part of the core curriculum. Private group training can be arranged for workplaces, schools, community organizations, and students who want practical emergency first aid skills when it matters most.
Key Takeaway
In a trauma emergency, follow Check, Call, Care. Control severe bleeding using direct pressure, wound packing, or a tourniquet. Begin CPR if the person has no pulse. Treat shock by keeping the person lying down, warm, and calm. A person can bleed to death in 3 to 5 minutes, making bystander emergency first aid help critical before emergency medical services arrive. First aid certification in Canada is valid for 3 years under CSA Z1210:24 standards.

A: First aid is the immediate care given to someone who is ill or injured, involving simple, life-saving techniques that can be performed by anyone. Emergency first aid focuses specifically on stabilizing a person with a life-threatening condition until emergency medical services arrive. It covers severe bleeding control, CPR, shock management, choking response, and chest wound treatment. An emergency first aid course teaches these skills through hands-on practice and real-life scenarios.
A: Controlling severe bleeding is the most critical skill in a mass casualty event. Hemorrhage is the number one cause of preventable death in trauma situations, and a person can bleed to death in three to five minutes. Prompt action using direct pressure, wound packing, or tourniquet application prevents severe blood loss and potential shock. Everyone should know these techniques before an emergency occurs.
A: Apply firm, direct pressure to the wound using a clean cloth, sterile dressing, or your hands. Do not remove the dressing if blood soaks through. Add more material on top. For deep wounds in areas where a tourniquet cannot be applied, pack the wound with clean material and apply pressure. For severe limb bleeding, apply a tourniquet 5 to 7 centimetres above the wound and tighten until bleeding stops. Note the time of application and inform paramedics on arrival.
A: Begin CPR if an injured person has no pulse and is not breathing. Cardiopulmonary resuscitation keeps oxygen flowing to the brain and organs when the heart stops. In a mass casualty event with multiple victims, prioritize severe bleeding control before CPR, as bleeding control helps more potentially survivable victims. If an AED is available, use it as soon as possible. CPR should be continued until emergency medical services arrive and take over.
A: Check, Call, Care is the standard protocol for responding to a medical emergency. Check the scene to ensure it is safe for you to approach. Call 911 or instruct someone nearby to call while you begin providing care. Care for the injured person using the first aid techniques appropriate to their injuries. This framework is the foundation of every basic first aid course and ensures that rescuers act in a safe, organized, and effective way.
A: Keep the victim lying down with legs elevated approximately 30 centimetres if their injuries allow. Cover them with a blanket or jacket to maintain body temperature. Do not give them anything to eat or drink. Reassure them calmly and monitor their breathing continuously. Call 911 immediately. Shock can occur rapidly after severe trauma or heavy blood loss and is a life-threatening emergency requiring professional medical care as quickly as possible.
A: A trauma-focused emergency first aid kit should include a commercial tourniquet, hemostatic gauze, chest seals, compression bandages, sterile dressings, nitrile gloves, a CPR face shield, and an emergency blanket. These aid kits are compact enough for a backpack or vehicle glove compartment. Having the right supplies available before an emergency allows you to act immediately without improvising. Many first aid training providers recommend specific trauma kits as part of their courses.

Employers must ensure employees hold current first aid certification to comply with occupational health and safety regulations.
A: Basic Emergency First Aid is a shorter course covering essential life-saving skills including CPR, AED, bleeding control, and choking response. Standard First Aid is a more comprehensive course that adds deeper coverage of medical emergencies, trauma management, head injuries, hypothermia, severe burns, stroke recognition, and workplace-specific scenarios. Standard First Aid meets the requirements for most Canadian workplaces and provides broader competence across common medical emergencies.
A: If a chest wound is bubbling or making a sucking sound, it is a sucking chest wound indicating air is entering the chest cavity. Cover the wound with a non-porous material, sealing three sides and leaving one side open to allow air to escape. This improvised chest seal prevents a tension pneumothorax. Call 911 immediately and keep the injured person as still as possible while monitoring their breathing.
A: The Platinum Ten Minutes refers to the first ten minutes after a traumatic injury, during which immediate first aid intervention has the greatest impact on survival. Hemorrhage control and airway management in this window can prevent the progression of a survivable injury to a fatal one. This concept underlines why waiting for emergency medical services is not sufficient when someone is experiencing severe blood loss. Bystander emergency first aid help fills this critical gap.
A: The Emergency Medical Responder (EMR) program is an advanced pre-hospital care training course that goes significantly beyond basic first aid. EMR training covers advanced patient assessments, airway management, oxygen therapy, spinal motion restriction, trauma management, and multiple casualty incident response. It is recommended for firefighters, security professionals, industrial workers in remote locations, and anyone pursuing a career in emergency services. EMR certification is the highest level of bystander emergency care training available in Canada.

An AED (Automated External Defibrillator) is a portable device that analyzes the heart’s rhythm and delivers an electrical shock to restore a normal heartbeat during sudden cardiac arrest. AEDs are found in airports, malls, schools, gyms, office buildings, and government buildings across Canada. Look for a red or green sign with a white heart and lightning bolt. Every minute without defibrillation reduces survival by 7 to 10 percent. Using an AED within the first few minutes increases survival rates to 70 percent or higher.

An Automated External Defibrillator (AED) is a portable electronic medical device that analyzes the heart’s electrical activity to assess the heart’s rhythm and delivers an electrical shock if necessary to restore a normal heartbeat during sudden cardiac arrest. Sudden cardiac arrest occurs when the heart stops beating unexpectedly, leading to a lack of blood flow to the brain and other organs. Without immediate intervention, brain damage begins within 4 to 6 minutes and death follows shortly after.
When someone experiences sudden cardiac arrest, their heart stops beating effectively and begins to quiver in an abnormal rhythm called ventricular fibrillation. Only defibrillation, the delivery of a controlled electrical shock, can stop this chaotic electrical activity and allow the heart’s natural pacemaker to restart. CPR alone cannot restore a normal heartbeat in ventricular fibrillation. An AED is the only tool that can deliver this life-saving shock outside of a hospital setting.
AEDs are designed to be user-friendly, providing clear voice prompts and visual instructions to guide users through the process of delivering a shock if needed. The device will not shock someone who does not need it. The AED’s internal computer evaluates the heart’s rhythm and only advises a shock when a shockable rhythm is detected. This built-in safety feature makes AEDs one of the safest and most effective medical devices available to the general public, especially when users also follow the manufacturer’s specific safety instructions.
When you power on an AED and attach the electrode pads to the patient’s bare chest, the device immediately begins analyzing the heart’s electrical activity. The AED’s internal computer evaluates the heart rhythm and determines whether a shock is needed. If the rhythm is shockable, the device charges and instructs the user to press the shock button. Some fully automatic AED models deliver the shock without requiring the user to press anything. In 2026, smart-city initiatives in Canada have begun linking public AED units to emergency dispatch apps, allowing bystanders to be alerted to the nearest device in real-time.
AED pads, also called electrode pads, are adhesive patches that stick to the patient’s bare chest and connect the device to the patient’s body. One pad is placed on the upper right chest below the collarbone, and the other pad is placed on the lower left side of the chest. The pads both deliver the electrical shock and record the heart’s rhythm for analysis. AED accessories such as pads and batteries have expiration dates and must be replaced on schedule to ensure the device is ready in an emergency. Electrode pads are single-use and must be replaced after each use.
AEDs provide clear voice prompts at every step, telling the user exactly what to do from the moment the device is powered on. The device will instruct the user to attach the pads, stand clear while it analyzes the heart rhythm, and press the shock button if a shock is advised. Before pressing the shock button, the user must loudly announce that everyone should stand clear and visually confirm that nobody is touching the patient. Some AED models also display visual instructions on a small screen alongside the voice prompts, making the device accessible even in loud environments.
Sudden cardiac arrest is not the same as a heart attack. A heart attack is a circulation problem caused by a blocked artery. Sudden cardiac arrest is an electrical problem where the heart’s rhythm becomes so chaotic that the heart stops pumping blood entirely. The two conditions can occur together, but they are distinct medical emergencies requiring different responses.
During a cardiac arrest, the chances of survival decrease by approximately 10 percent for every minute that passes without defibrillation. Emergency medical services in Canada typically take 8 to 12 minutes to arrive on scene. By the time paramedics arrive, a victim who has not received defibrillation faces survival odds of less than 10 percent. When a bystander uses an AED within the first few minutes, survival rates increase to 70 percent or higher. This gap between when cardiac arrest occurs and when emergency medical services arrive is precisely why public access AED programs save thousands of lives every year: trained bystanders and other first responders can act before EMS arrives.
The use of an AED in the field also provides a critical head start for the medical team at the emergency room. When an AED is applied, it records the heart’s rhythm data, which can later be downloaded by physicians to determine the exact cause of the cardiac event. This data allows cardiologists to decide immediately if a patient needs an emergency stent, a pacemaker, or specific medication. If a shock was delivered successfully before paramedics arrived, the patient’s chances of reaching the emergency room with intact neurological function increase by over 60 percent.
AEDs are becoming increasingly common in public spaces throughout Canada. The universal symbol for AEDs is a red or green sign featuring a white heart with a lightning bolt. It is possible to check signage and main visual hubs like elevators and lobbies to locate an AED. Community safety apps like PulsePoint AED can also help locate nearby AED units quickly.
Many Canadian employers now include AEDs as part of their workplace safety equipment. Office towers, factories, warehouses, and government buildings frequently have AED units installed on each floor or in centralized locations. Knowing where the AED is located in your building before an emergency occurs significantly reduces response time. Corporate first aid training programs often include AED training to ensure employees can respond effectively.
Educational institutions from elementary schools to universities often have AEDs installed in gymnasiums, main offices, and common areas to protect students, staff, and visitors. Given the number of young athletes participating in physical activities, having AEDs readily available is particularly important. Major Canadian airports including Toronto Pearson, Vancouver International, and Montreal-Trudeau have AEDs placed throughout their terminals. Large shopping centres across Canada are increasingly required to have AEDs on site, typically located near customer service desks, food courts, or security offices. Gyms, recreational centres, arenas, community pools, and aquatic centres also have AEDs available as part of their safety protocols. Libraries, community halls, churches, mosques, temples, and other gathering places increasingly have AEDs available, particularly important given the older adult populations these venues often serve.

If your workplace, school, or community organization owns an AED, regular maintenance is essential to ensure the device is always ready when needed. When you purchase a unit or replacement accessories, verify that they are Health Canada approved where applicable. AED batteries typically last 2 to 5 years, and electrode pads have expiration dates that must be monitored. Most modern AEDs perform automatic self-checks and display a status indicator, usually a green checkmark or flashing light, to confirm the device is operational, though users should still follow the manufacturer’s specific safety guidance for inspection and use. AED accessories including replacement pads, batteries, and carry cases should be stocked on hand so the device can be returned to service immediately after use.
Designate someone in your organization to perform monthly visual inspections and keep a maintenance log to track battery and pad replacement schedules. Some AED units can be registered with local emergency services so that dispatchers know their location and can direct bystanders to them in a cardiac emergency. Registering your AED with your provincial AED registry is a simple step that increases the likelihood of your device being used effectively.
While AEDs are designed to be intuitive, proper first aid training and AED training significantly increase your confidence and effectiveness in a cardiac emergency. Proper training on the use of an AED significantly increases the confidence and effectiveness of a bystander in an emergency situation.
AED training courses offered through the Canadian Red Cross provide comprehensive hands-on aid training that covers AED operation, CPR techniques, and how to manage a cardiac emergency from start to finish. CPR and AED certification courses include hands-on practice, real-life scenarios, and step-by-step instruction to ensure participants can respond effectively under pressure. In a cardiac emergency, trained bystanders perform better because practiced skills take over when the mind is overwhelmed by stress.
Cardiopulmonary resuscitation keeps oxygen flowing to the brain and organs when a person’s heart stops. When combined with early defibrillation using an AED, CPR and AED together represent the most powerful bystander intervention available during sudden cardiac arrest. Begin CPR immediately when someone collapses and is unresponsive. Continue CPR until the AED is powered on and ready to analyze the heart rhythm.
Understanding the cardiac science behind why AEDs work helps bystanders act with confidence. Ventricular fibrillation causes the heart’s electrical system to fire chaotically, disrupting the heart’s electrical activity and preventing coordinated contraction. An electrical shock delivered by an AED essentially resets the heart’s electrical system, helping restore normal function so the natural pacemaker has a chance to resume its rhythm. For those who prefer flexible scheduling, blended learning options are available, allowing you to complete the theory portion of AED training at your own pace before attending a shorter hands-on skills session. Employers looking to train their entire team can arrange private group training sessions at their workplace for maximum convenience.
Many Canadians hesitate to use an AED because they worry about legal liability. The good news is that every Canadian province has Good Samaritan legislation that protects bystanders who provide emergency assistance in good faith. If you use an AED to help someone experiencing cardiac arrest, you are legally protected from liability as long as you are acting reasonably and without gross negligence. These laws exist specifically to encourage bystander intervention, because the alternative, doing nothing, almost certainly results in death.
Ontario’s Chase McEachern Act (Heart Defibrillator Civil Liability Act) provides specific legal protection for AED users and encourages broader AED placement in public spaces. Several provinces have also enacted legislation requiring AEDs in certain public buildings and mandating that staff receive training in their use. The combination of public access AEDs, widespread first aid training, and Good Samaritan legal protection creates the conditions needed for communities to save thousands of lives each year from sudden cardiac arrest.
While AEDs are designed to be intuitive, understanding the basic steps beforehand builds the confidence to act quickly in a cardiac emergency, and early action by bystanders often makes them the first responders before EMS arrives.
Key Takeaway
An AED analyzes the heart’s rhythm and delivers an electrical shock to restore a normal heartbeat during sudden cardiac arrest. Survival rates reach 70 percent or higher when an AED is used within the first few minutes, compared to less than 10 percent when defibrillation is delayed. AEDs are found in airports, schools, gyms, malls, office buildings, and government buildings across Canada. Look for the red or green heart-and-lightning-bolt sign. You are legally protected by Good Samaritan laws when using an AED in good faith.

If one thing’s sure enough, it’s this: Toronto will be absolutely hot throughout the summer. In response, many folks within the region head for the water on the weekends and holidays. Whether it’s in the form of a backyard or community pool, a beach, getting wet is that the best way to remain cool throughout the scorching summer months. However, along with all of the fun of swimming comes several dangers. In fact, drowning number one cause of accidental death for Torontonians kids aged zero to five years. These serious statistics highlight the importance of being as safe as possible when by the water this summer – and could be a reminder of the advantages of taking swimming lessons, as well.
