Cardiopulmonary Resuscitation (CPR) (cont.)

Cardiac Arrest

When a person develops cardiac arrest, the heart stops beating. There is no blood flow and no pulse. With no blood flowing to the brain, the person becomes unresponsive and stops breathing normally.

  1. When you discover a person whom you believe is experiencing a medical emergency, the first thing to do is check for responsiveness. Gently shake the victim and shout, "Are you OK?"
  2. If the person does not respond to your voice or touch, they are unresponsive. If the victim is unresponsive and you are alone, leave the victim and immediately call 911. If someone is with you, tell him or her to call 911 and then return to help you.
  3. If an AED is available, bring it back to the person's side. The moment an AED becomes available, IMMEDIATELY press the "on" button. The AED will begin to speak to you. Follow the directions to use the AED.

This American Heart Association video demonstrates the steps to provide CPR to cardiac arrest victim.
