Correct Use of a Defibrillator (AED) in the Workplace or Home: A First Aid Trainer’s Guide

Automated External Defibrillators (AEDs) are lifesaving devices that can restore a normal heart rhythm during sudden cardiac arrest. When used promptly and correctly, they dramatically increase survival rates. Here’s how to operate an AED safely and effectively in any setting.

1. Recognize Cardiac Arrest

Check responsiveness: Tap the person’s shoulders and shout.
Confirm absence of breathing or gasping: If unresponsive and not breathing normally, begin CPR and send someone to retrieve the AED.

2. Prepare the AED

Power on the device: Open the AED case and follow voice/visual prompts.
Expose the chest: Remove clothing and jewelry. Dry or shave the chest if necessary (use the included razor).

3. Apply Electrode Pads

Place pads correctly:
- Adult: One pad on the upper right chest, the other on the lower left side (below the armpit).
- Child/infant: Use pediatric pads if available, placing one pad on the chest and the other on the back.
Ensure good contact: Press firmly to adhere pads to bare skin.

4. Analyze the Rhythm

Stand clear: Ensure no one touches the person. The AED will analyze the heart rhythm.
Shock advised? If the AED detects a shockable rhythm (e.g., ventricular fibrillation), it will charge and prompt you to press the shock button.

5. Deliver the Shock

Clear the area: Loudly announce, “Stand clear!” and verify no one is touching the person.
Administer the shock: Press the flashing shock button.

6. Resume CPR

Start compressions immediately after the shock (30 compressions followed by 2 breaths).
Follow AED prompts: It will reanalyze every 2 minutes and advise further shocks if needed.

What NOT to Do

Do not use on a conscious person with a pulse.
Do not remove pads once applied—leave them in place for EMS.
Avoid delays: Minimize interruptions in CPR.

AED Maintenance

Check expiration dates on pads and batteries monthly.
Store in visible, accessible locations (e.g., workplace entrances, home kitchens).

Why Training Matters

AEDs are designed for public use, but practice builds confidence. Attend CPR/AED courses to master pad placement, rhythm analysis, and teamwork.

Final Thoughts

Every minute without defibrillation reduces survival chances by 7–10%. By keeping AEDs accessible and training responders, workplaces and homes can turn bystanders into lifesavers. Stay calm, trust the device, and act swiftly—it could save a life.
