How to Use an AED: A Life-Saving Guide for the Public

Sudden cardiac arrest can happen to anyone, anywhere. In these critical moments, having an Automated External Defibrillator (AED) on hand and knowing how to use it can mean the difference between life and death. At Trainer Hub, we believe that everyone should feel confident in using an AED, whether you’re a first aid trainee or a member of the public.

What is an AED?

An Automated External Defibrillator (AED) is a portable device that checks a person’s heart rhythm and delivers a controlled electric shock if needed to restore a normal heartbeat. AEDs are designed to be simple and user-friendly, making them accessible even to those with little or no medical training.

When to Use an AED

You should use an AED when someone:

• Is unresponsive and not breathing normally

• Has collapsed suddenly

• Shows no signs of life (no pulse, no movement, no breathing)

If you suspect cardiac arrest, call 999 immediately and begin CPR while someone fetches an AED.

How to Find an AED

Locating an AED quickly is crucial in an emergency. Here’s how you can find one:

• Call 999 – The emergency operator can tell you where the nearest publicly accessible AED is located.

• Look for Yellow Boxes – Many AEDs are stored in bright yellow, locked cabinets in public places such as shopping centres, train stations, and community hubs.

• Use The Circuit – The British Heart Foundation’s database, The Circuit, maps public defibrillators across the UK. You can search online for your nearest AED. However, not all defibrillators are listed, so always be prepared to check locally.

• Check Availability – Some AEDs may not be available 24/7, especially if they are inside buildings with restricted access.

How to Use an AED: Step-by-Step Guide

1. Turn It On – AEDs will typically have a power button or will turn on automatically when opened.

2. Follow the Voice Prompts – AEDs provide clear, step-by-step instructions to guide you.

3. Expose the Chest – Remove any clothing covering the chest. If the chest is wet, dry it off.

4. Attach the Pads – Place one pad on the upper right side of the chest and the other on the lower left side.

5. Let the AED Analyse – The device will assess the heart rhythm and determine if a shock is needed.

6. Deliver the Shock (If Advised) – If prompted, ensure no one is touching the person and press the shock button.

7. Continue CPR – If no shock is advised or after delivering the shock, continue chest compressions until emergency services arrive.

Key Tips for Using an AED

• Don’t hesitate – AEDs are designed for public use and won’t deliver a shock unless necessary.

• Stay calm and listen to the prompts – The device will guide you every step of the way.

• Continue CPR when needed – Even after using an AED, high-quality CPR is crucial.

• Know where AEDs are located – Many public places, workplaces, and community centres have AEDs. Look for signs indicating their presence.
