Buying an AED in Canada: 8 Key Questions to Choose the Right Defibrillator

Buying an AED in Canada is a decision that can directly impact a person’s chance of survival. When a sudden cardiac arrest occurs, every minute without defibrillation or CPR reduces the likelihood of survival, so having the right equipment and CPR training matters.

At the same time, choosing an AED is not always straightforward, especially when we do not have information about this kind of device. So it’s critical to get familiar with them in order to be able to ask the proper questions and make the most of this outlay.

In this guide, we outline eight key questions to help you select the most suitable AED for your needs in Canada—ensuring you make a confident, informed investment in cardioprotection.

What is an AED and how does it work?

AED stands for Automated External Defibrillator. An AED is a device designed to automatically analyze the heart’s electrical activity in a victim with suspected sudden cardiac arrest (unresponsive, not breathing, no pulse).

The device can detect whether the heart rhythm is shockable. If so, it delivers a controlled electrical shock (measured in joules) to help restore a normal heart rhythm. Early use of an AED in Canada significantly increases survival rates in cases of cardiac arrest.

Who can use an AED in Canada?

In theory, anyone can use an AED, as these devices are designed to be simple and intuitive. However, it is strongly recommended that they are operated by trained individuals.

CPR and AED training is straightforward and specifically designed for non-healthcare professionals, making it accessible for workplace staff, safety teams, and the general public.

Automatic vs. semi-automatic AED: which one should you choose?

There are two main types of AEDs: fully automatic AEDs and semi-automatic AEDs. Both are designed for use by non-medical personnel, often referred to as first responders.

In workplaces or public spaces where designated responders are trained, a fully automatic AED is often the best option. The user simply follows voice and visual prompts, and the device delivers the shock automatically if needed.

On the other hand, in environments with healthcare professionals, a semi-automatic AED may be preferred, as it allows the operator to decide when to deliver the shock based on clinical judgment.

What type of waveform and energy level should an AED have?

International guidelines, such as those from the American Heart Association and the European Resuscitation Council, recommend biphasic waveform technology for AEDs, as it reduces damage to the heart muscle.

Modern AEDs typically deliver shocks between 120 and 200 joules when using biphasic technology, which is considered safe and effective for treating sudden cardiac arrest.

AED batteries: rechargeable or long-life lithium?

Rechargeable batteries are increasingly being replaced by long-life lithium batteries (LiMnO₂) in modern AEDs, as they offer longer standby time and lower maintenance requirements. Rechargeable batteries require more frequent checks and timely recharging to ensure the device is always operational.

It is also important to note that the battery should always remain installed in the AED, even when not in use, so the device can perform automatic self-tests and alert users if maintenance is needed.

Why are AED self-tests and maintenance alerts important?

It is essential that an AED includes automatic self-testing features. These systems regularly check the device’s status and provide visual or audible alerts if an issue is detected.

This ensures that the AED is always ready for use in an emergency and reduces the risk of device failure during a cardiac arrest response.

Should an AED have an automatic shut-off feature?

Yes, an AED should include an automatic shut-off function. This feature turns the device off after a period of inactivity, helping preserve battery life and ensuring long-term readiness.

Should I buy pediatric AED pads?

If the AED will be installed in a location where children under 8 years old or under 25 kg may be present, it is recommended to have pediatric AED pads available. These pads are single-use and designed to deliver an adjusted shock appropriate for children. Many AEDs can automatically detect pediatric pads and reduce the energy level accordingly.

In addition, SCHILLER’s FRED PA-1 and FRED PA-1 Online offer an adult–pediatric adapter. This adapter allows adult pads to be connected and recognized as child pads, ensuring the correct energy level is applied.

Where to buy an AED in Canada: choosing the right supplier

Once you’ve worked through these eight questions, the priority is clear: your AED must be reliable, supported, and ready to use at any time.

Where you buy your AED in Canada plays a key role in that. Working with a supplier that has local representation helps ensure consistent access to AED accessories, consumables, replacement parts, and ongoing support when you need it.

Access to certified local AED service is equally important. It allows for faster maintenance, reduces downtime, and avoids the cost and delays of sending the device back to the manufacturer.
