How to use an AED

Sudden cardiac arrest happens without warning. A person will suddenly collapse, stop breathing, have no pulse and lose consciousness.

Follow these steps if someone has sudden cardiac arrest and an AED is nearby.

1. Check to see if the person is breathing and if they have a pulse.
2. If there is no breathing or pulse, call 911 or local emergency services right away. If you are alone, call for help first. Then get an AED if one is nearby. If someone else is there, one person can start CPR and another can call for help and get the AED.
3. Turn on the AED. The AED gives you step-by-step voice instructions. It tells you how to check for breathing and a pulse. It tells you how and where to put the AED pads on the person's chest.
4. Stand clear and deliver the shock. After placing the pads, step away from the person. If the AED says a shock is needed, make sure no one is touching the person. Say "stand clear" loudly, and push the shock button. The AED gives a shock only when needed.
5. Start CPR after the shock, if needed. The AED guides you through the CPR steps. You can repeat these steps until emergency medical help arrives.
