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

To use an AED defibrillator, check that the person is unresponsive and not breathing normally, call 999 or 112, and begin CPR. Ask someone to bring an AED, switch it on, attach the pads to the person’s bare chest, and follow its voice or visual instructions. The AED will analyze the heart rhythm and tell you whether a shock is required.

What Is an AED Defibrillator?

An AED, or Automated External Defibrillator, is a portable device used during sudden cardiac arrest. It analyses the heart’s electrical rhythm and, when appropriate, delivers an electrical shock.

AEDs provide voice and visual instructions, helping guide the user through the process. However, knowing the basic steps and having hands-on training can help you respond more effectively in an emergency.

When Should You Use an AED?

An AED should be used when someone is unresponsive and not breathing normally.

If this happens:

• Check that the area is safe.

• Check the person’s responsiveness and breathing.

• Call 999 or 112.

• Ask someone to get an AED.

• Start CPR.

• Use the AED as soon as it arrives.

  
  

Acting quickly is important, so do not wait for the AED before starting CPR.

How to Use a Defibrillator Step by Step

You can break down defibrillator use into a few clear steps.

1. Check the Person and Call for Help

Check whether the person responds and is breathing normally. If they are unresponsive and not breathing normally, call 999 or 112 immediately.

Ask someone nearby to bring the nearest AED while you begin CPR.

2. Turn On the AED

When the AED arrives, switch it on. Some devices turn on automatically when you open the lid.

Listen carefully to the device's instructions and follow them throughout.

3. Attach the AED Pads

Expose the person’s chest and place the electrode pads directly onto the bare skin.

Follow the diagrams on the pads to position them correctly. Make sure the pads are firmly attached.

If the chest is wet, dry it before applying the pads.

4. Let the AED Analyse

Once the pads are connected, the AED will analyze the person’s heart rhythm.

Do not touch the person during analysis.

The AED will determine whether a shock is advised and tell you what to do next.

5. Deliver the Shock if Advised

If the AED advises a shock, make sure everyone stands clear and nobody is touching the person.

Follow the device’s instructions to deliver the shock. Some AEDs require the user to press a button, while others deliver the shock automatically.

6. Continue CPR

After the shock, or if no shock is advised, follow the AED’s instructions. Resume CPR when instructed and continue until emergency medical professionals arrive or the person shows signs of life.

How Does an AED Work?

An AED analyses the heart's electrical activity through pads attached to the chest. It identifies whether the heart rhythm may require defibrillation.

Importantly, an AED does not simply deliver a shock whenever it is switched on. It analyses the rhythm first and provides instructions based on its findings.

That’s why following the device’s prompts is essential.
