Automated External Defibrillator (AED)

Automated External Defibrillators (AEDs) save lives at work, home and play.

About 40,000 Canadian experience cardiac arrest every year. That’s one cardiac arrest every 12 minutes.

Defibrillation improves survival rates by up to 30% if delivered in the first few minutes. With each passing minute, the probability of survival declines by 7 to 10%. Making defibrillators easily accessible has the potential to save thousands of lives.

FREE Pad-PakTM Program

If you have used a HeartSine samaritan PAD during a Sudden Cardiac Arrest (SCA) in a public setting, it’s critical that you TELL US, by providing HeartSine with the Saver EVO file that contains comprehensive event data about the event and a completed Customer Event Report form.

Two simple steps

1. Immediately after a HeartSine AED is used during an SCA, download the event data file (.evo) from your AED.

2. Complete and submit the following to :

  • HeartSine Customer Event Report form (with no identifying patient information)
  •  Event file (.evo)

If the event qualifies and the information provided is complete, a free Pad-Pak will be shipped to you. Please allow two business days for review of the event data.

The Saver EVO software and manual, and the Customer Event Report form are available at

Differences Between Models

All AEDs are easy to use and possess three basic elements, a battery, a main unit that analyzes heart rhythm and generates the electrical charge and pads that deliver the shock. 

Aside from the basic elements, there are features that can differentiate one model from the next 

Warranty Duration

New AEDs tend come with a manufacturer’s warranty ranging from 5-10 years. 

Battery Life & Type
Battery life varies, which can impact the overall cost of an AED.

Shock Levels
Some AEDs feature fixed energy, while others have variable energy based on body mass and composition. In some models, energy can also escalate from one shock to the next. 

Semi vs. Fully Automatic Semi-automatic
Semi-automatic AEDs require the user to press a button to deliver the shock, while fully automatic AEDs administer the shock automatically when appropriate. 

Voice-Prompting & CPR Coaching
All AEDs feature voice prompts to guide the user through defibrillation. Some AEDs also feature CPR coaching. 

All AEDs perform periodic internal circuitry and battery checks and will alert you if there is a problem. Some AEDs also check for energy flow to the pads. 


This is measured by two factors: The Ingress Protection (IPX) rating, which measures resistance to dust (first IP number) and water (second IP number); and drop height measurements. The higher the IPX number, the greater the water and dust resistance. 

St. John Ambulance considers it everyone’s business to care about mental health and wellness in the workplace. It’s why we developed a new 1-day, peer-to-peer mental health course: Mental Health & Wellness for the Workplace.

One in three Canadians will experience a mental health injury at some point during their life. The earlier an injury is detected and treated, the better the outcome.


An Automated External Defibrillator (AED) is a device that can monitor heart rhythms. It can tell if the heart has stopped beating effectively. If required, the machine will deliver an electric shock to the heart. Automated External Defibrillators (AEDs) are so easy to use that they make it possible for any bystander to potentially save a life. 

Approximately 40,000 cardiac arrests occur in Canada every year – 80% outside of a hospital setting. With each passing minute, the probability of survival declines by 7% to 10%. Defibrillation improves survival rates by up to 30% if delivered in the first few minutes. AEDs combined with Cardiopulmonary Resuscitation (CPR) increases survival rates to 50% or more.  

Making defibrillators easily accessible in public buildings such as hockey arenas, shopping malls, airports, etc. has the potential to save lives. 

An AED is very simple to use yet houses the same sophisticated defibrillation technology relied on by emergency medical services. 

An AED is programmed to recognize and shock two types of abnormal heart rhythms: Ventricular Fibrillation (VF) and Pulseless Ventricular Tachycardia (Pulseless VT). Because of this, it will not shock a normally beating heart. 


If an AED recognizes either of these rhythms, it will charge and indicate that a shock is advised, usually with a voice command. The benefit of the shock is to correct the abnormal electrical disturbance that is causing the irregular heart rhythm, and re-establish a normal heart rhythm. 
Be aware that legislation in most provinces and territories across Canada protects individuals who use AEDs from liability when they are used in the context of saving a life, so don’t be afraid to intervene! The only provinces and territory without Good Samaritan laws are New Brunswick and Nunavut. 

Because all AEDs emit clear voice prompts and most have legible and visual instructions, they can be used by anyone, regardless of age of experience. In fact, using an AED is one of the easiest first aid techniques you can master. 
Once you press the ON button or open the cover on an AED, it will guide you through the following step-by-step process with clear voice prompts 


In 1883 Quebec City was the first Canadian branch to teach first aid courses and shortly thereafter courses were being offered in Kingston, Ontario. In the next 10 years, St. John Ambulance grew to be a national organization and by 1892 had 12 branches teaching first aid from coast-to-coast.   

Today, in more than 300 communities across Canada more than 10,000 St. John Ambulance volunteers provide over one million hours of community service per year. The financial contribution of St. John volunteers could be calculated in hundreds of millions of dollars. The contribution to safety of Canadians is immeasurable.  

St. John Ambulance offers classes at nearly 100 locations across Canada, as well as some online courses.
