An automated external defibrillator (AED) is a lightweight, portable device. It delivers an electric shock through the
chest to the heart when it detects an abnormal rhythm and changes the rhythm back to normal.
AEDs help people who have a sudden cardiac arrest, which occurs when the heart suddenly stops beating regularly.
This happens when the heart’s natural electrical system doesn’t work correctly. If not treated within minutes, cardiac
arrest quickly leads to death.
AED Facts & Statistics
- CPR combined with using an AED provides the best chance of saving a life. If possible, use an AED every time you provide CPR.
- A person’s chance of survival drops by 7% to 10% every minute a normal heartbeat isn’t restored
- AEDs are intended for use by the general public (or lay responders). They are portable, safe, accurate, and easy to use.
- AEDs are accurate in detecting when (or when not) to deliver a shock.
How does an AED Work - Quick Tips
The AED uses voice prompts, lights, and text to tell the rescuer the steps to take.
AEDs may have 2 sets of pads: adult pads and child pads. For CPR, anyone 1 year or older who hasn’t gone through
puberty is considered a child. However, for defibrillation, make sure you use the adult pads for anyone 8 years or older.
Follow these steps when using the AED:
- Turn on the AED and follow the voice prompts.
- Remove all clothing covering the chest. If necessary, wipe the chest dry
- Peel away the backing from the pads and attach the pads to the person’s bare chest following the illustration on the pads.
- Plug the pads connector into the AED, if necessary.
- The AED will check to see if the person needs a shock and tell you when to give one. While the AED is analyzing, make sure no one is touching the person.
- Resume CPR if no shock is needed. If a shock is needed, make sure no one is touching the person and press the Shock button, and then immediately resume CPR.
- Continue CPR until emergency medical personnel arrive.
