AED Defibrillators

What is a defibrillator?
A defibrillator is a portable medical device designed to be used in emergencies where someone collapses due to a cardiac event. Most modern defibrillators are AEDs (automated external defibrillators) and are found in workplaces, schools and public spaces.

What does a defibrillator do?
A defibrillator is a medical device that can detect dangerous heart rhythms. If it detects a sudden cardiac arrest, it then delivers an electric shock to restore a normal heart rhythm. It’s designed to restart the heart safely and quickly.

Is a defibrillator the same as an AED?
Yes. An automated external defibrillator (AED) is a type of portable defibrillator designed for public and workplace use.

How do AED defibrillators work?
Automated external defibrillators are used to treat sudden cardiac arrest by delivering a controlled shock that helps the heart re-establish a stable rhythm. Fast action with a defibrillator can save lives.

Is it worth buying a defibrillator for home?
Yes, having a home defibrillator can be valuable, especially if someone in the household is at risk of cardiac arrest. It offers peace of mind and immediate access in emergencies.

Do I need a defibrillator at work?
Yes, it is recommended to have one at work. Many workplaces choose to have an automated defibrillator at their workplace to improve emergency preparedness and protect employees and visitors. A workplace defibrillator can be critical during a cardiac arrest.

Are defibrillators easy to use?
Yes, modern AED defibrillators are designed for people with little or no medical training to use. They provide clear instructions, visual guidance and automatic analysis to help users act quickly and confidently.

Who should not use an AED defibrillator?
A defibrillator should not be used on someone who is breathing normally or has a pulse. Automated external defibrillators are only for unresponsive people who are not breathing or showing signs of life.

Is an ICD a defibrillator?
Yes, an Implantable Cardioverter Defibrillator (ICD) is a type of defibrillator. It’s surgically placed inside the body to monitor and correct dangerous heart rhythms automatically when needed.

What is the difference between a fully automatic and a semi-automatic defibrillator?
A fully automatic AED defibrillator delivers a shock on its own after detecting an irregular rhythm. A semi-automatic AED guides the user to press a button when it’s time to shock.

Why is a defibrillator used in CPR?
Defibrillators are used alongside CPR to restore the heart’s normal rhythm during cardiac arrest. The shock works to stop irregular electrical activity so the heart can beat effectively again.

Can I use a defibrillator on a child?
Yes, you can use a defibrillator on a child. Most AEDs have child-specific pads or a switch for paediatric use. Always follow the device’s instructions to ensure safe treatment.

Where are defibrillators commonly found?
Defibrillators are often placed in public areas like airports, schools, gyms, offices, and shopping centres. These locations are chosen for high foot traffic and quick access during emergencies.

What should you avoid with a defibrillator?
The most common mistake when using automated external defibrillators is delaying the shock or failing to follow the voice prompts. Staying calm, listening carefully, and acting fast improves the chance of saving a life.
