Use it as soon as possible when someone:
- is unresponsive, and
- is not breathing normally (including gasping)
That combination strongly indicates cardiac arrest, and the Automated External Defibrillator (AED) should be applied immediately alongside Cardiopulmonary Resuscitation (CPR).
- If the person has a pulse and is breathing, do NOT do CPR.
- Keep them comfortable, call 000, and monitor them. CPR is only for cardiac arrest.
What to do:
- Call 000 (or have someone else call). (call 112 from a mobile phone anywhere in the World)
- Start CPR immediately (30 compressions, 2 breaths, or hands-only if unsure).
- Get an AED and turn it on right away.
- Follow the voice prompts — the device decides if a shock is needed.
- Continue CPR between prompts.
About safety and use:
- AEDs are designed for bystanders or the public — you won’t “accidentally” shock someone who doesn’t need it.
- They can be used on children and pregnant people (use pediatric pads if available).
- Make sure the chest is dry and no one is touching the person during analysis/shock.
About the “10% per minute” rule:
It’s a useful rule of thumb, but real survival depends on multiple factors (early CPR, cause, location) every second and minute matters.
Here is a good checklist
🚑 AED + CPR Quick Checklist
1. Check
- Is the person responsive? (tap and shout)
- Are they breathing normally?
👉 If NO → act immediately
2. Call
- Call 000 or 112 from a mobile phone anywhere in the World.
- Put phone on speaker if you’re alone
3. Start CPR
- 30 chest compressions (hard, fast — centre of chest)
- 2 breaths (or hands-only if unsure)
- Keep going
4. Get AED
- Ask someone: “Get the defibrillator!”
- If alone: grab it if nearby, otherwise keep doing CPR
5. Turn AED ON
- Follow the voice prompts
- Expose chest, attach pads as shown or instructed by voice
6. Stand Clear
- Loudly say: “Clear!”
- Don’t touch the person during analysis/shock
7. Shock if Advised
- Press shock button if told
- Immediately resume CPR
8. Continue
- Follow prompts
- Keep going until:
- Help arrives, or
- The person starts breathing
🧠 Easy way to remember:
Check → Call → Compress → Connect → Clear → Continue
