AED (defibrillator) use

AEDs talk you through every step out loud. You cannot shock someone who doesn't need it — the device decides. Just turn it on and listen.
Serious — call 911 if in doubt

What to do now

  1. 1.Call 911 — start CPR now
  2. 2.Send someone for the nearest AED
  3. 3.Turn it on, follow the voice
  4. 4.Bare, dry chest — apply pads
  5. 5.Stand clear, deliver shock
  6. 6.Resume CPR immediately

For children:

  • Step 4 — Stand clear when it analyzes and shocks: Use pediatric pads for children under 8 if available. If not, adult pads are acceptable — place one on the chest and one on the back.
Steps

5 steps

  1. 1

    Call 911 and get the AED

    Send someone for the nearest AED while you start CPR. Most public buildings, gyms, and airports have one.

  2. 2

    Turn it on and follow voice prompts

    Power button is usually large and obvious. The device will speak each step.

    Tip: Modern AEDs cannot deliver an unnecessary shock. Trust it.
  3. 3

    Place the pads on bare, dry skin

    One pad upper right chest, one pad lower left side. Diagrams are printed on the pads. Cut or rip away clothing; dry the chest if wet.

    Important: Remove medication patches and wipe residue. Do not place pads over a pacemaker bump — offset by 1 inch.
  4. 4

    Stand clear when it analyzes and shocks

    Make sure no one is touching the person. Loudly say 'Clear!' Press shock if prompted.

  5. 5

    Resume CPR immediately after the shock

    Continue 30 compressions to 2 breaths until paramedics arrive or the person wakes.
