How to Use an AED (defibrillator) in Australia

A Simple, Life-Saving Guide Anyone Can Follow

Updated 30 March 2026

When someone collapses from sudden cardiac arrest, it’s confronting — and for many Australians, there’s a moment of hesitation.

“What if I do it wrong?”
“What if they’re a child… or pregnant?”
“Can I get in trouble?”

These are real concerns we hear every day.

The truth is this: doing something is always better than doing nothing.

AEDs are designed for everyday Australians — not just medical professionals. With calm voice prompts and built-in safety checks, they guide you every step of the way.

What Is an AED and When Should You Use It?

An Automated External Defibrillator (AED) is a portable device that delivers a controlled electric shock to the heart during sudden cardiac arrest.

Use an AED when someone:

Is unresponsive
Is not breathing normally
Has collapsed suddenly

Cardiac arrest can happen anywhere — at work, at sport, at home, or in public spaces. That’s why AED access and confidence matters for every Australian.

Step-by-Step: How to Use an AED

1. Check for Danger and Call 000

Ensure the scene is safe. Call 000 immediately.

2. Start CPR

Push hard and fast in the centre of the chest (100–120 compressions per minute).

3. Turn on the AED

Devices like the Zoll AED range will guide you with clear voice prompts.

4. Expose the Chest

Remove clothing and ensure the chest is dry.

5. Attach Pads

Follow the diagrams on the pads.

6. Stand Clear

The AED will analyse — do not touch the patient.

7. Deliver Shock

If prompted, press the shock button.

8. Continue CPR

Keep going until help arrives.

💡 Even Without an AED — You Can Still Prepare

Even if you don’t have access to a defibrillator, a chest prep kit ensures the patient is ready to receive a shock as soon as an AED arrives.

⚠️ Don’t Hesitate — You Can’t Do Harm

This is the biggest barrier we see across Australia.

AEDs will NOT shock unless it is needed.

You cannot make the situation worse — but waiting can.

You are also protected under Good Samaritan laws. If you act in good faith, you won’t get in trouble for helping.

Special Situations Australians Ask About

Children & Babies

Use paediatric pads if available. If not, use adult pads — don’t delay.

Pregnancy

Defibrillation is safe. Saving mum gives the baby the best chance.

Body Jewellery

Do not waste time removing it — place pads slightly away if needed.

Chest Preparation: The Step Most People Miss

For an AED to work properly, pads must stick firmly to the skin.

Dry the chest
Remove excessive hair
Clear obstructions

Why This Matters

Every minute without defibrillation reduces survival chances significantly.

But with early CPR and an AED, survival rates can dramatically improve.

This isn’t just for medical professionals — it’s for parents, teachers, tradies, coaches, and everyday Australians.

Confidence saves lives.
