A defibrillator is a life-saving device that delivers an electric shock to the heart in cases of sudden cardiac arrest. It helps restore a normal rhythm by stopping irregular heartbeats, giving the heart a chance to start beating properly again.

An AED (Automated External Defibrillator) is a type of defibrillator designed for public use. It gives clear instructions and can automatically analyse a heart’s rhythm to decide if a shock is needed. All AEDs are defibrillators, but not all defibrillators are AEDs.

Yes. AEDs are designed for use by members of the public with no medical training. They use voice and visual prompts to guide you through the process safely.

While training helps build confidence, AEDs are simple enough to use without it. Most models include clear instructions, visual diagrams, and voice prompts to guide you step by step.

A semi-automatic defibrillator requires you to press a button to deliver the shock. A fully automatic model delivers the shock itself after warning you to stand clear.
