How to Use an AED

These AED steps should be used when caring for a non-breathing child aged 8 or older who weighs more than 55 pounds, or an adult.

After checking the scene and ensuring that the person needs help, you should ask a bystander to call 911 for help, then:

1. Complete the CHECK and CALL steps

2. As soon as an AED is available, turn it on and follow the voice prompts

3. Remove clothing and attach pads correctly

Remove all clothing covering the chest. If necessary, wipe the chest dry

Place one pad on the upper right side of the chest

Place the other pad on the lower left side of the chest, a few inches below the left armpit

Note: If the pads may touch, place one pad in the middle of the chest and the other pad on the back, between the shoulder blades

4. Plug the pad connector cable into the AED, if necessary

5. Prepare to let the AED analyze the heart’s rhythm

Make sure no one is touching the person

Say, “CLEAR!” in a loud, commanding voice

6. Deliver a shock, if the AED determines one is needed

Make sure no one is touching the person

Say, “CLEAR!” in a loud, commanding voice

Push the “shock” button to deliver the shock

7. After the AED delivers the shock, or if no shock is advised, immediately start CPR, beginning with compressions.

Be prepared for moments that matter by taking an AED class and you could help save a life.
