8.5 CPR and AEDs

Notes

CPR (cardiopulmonary resuscitation) keeps blood moving to the brain and heart when someone's heart has stopped. Cardiac arrest is when the heart suddenly stops beating effectively.

• Signs: the person is unresponsive and not breathing normally (or only gasping).
• Steps: 1. check the scene is safe; 2. tap and shout "Are you OK?"; 3. call 911 (or tell someone to call and get an AED); 4. begin compressions.
• Hands-only CPR: push hard and fast in the center of the chest at a rate of 100 to 120 compressions per minute, about 2 inches (5 cm) deep for an adult. Let the chest rise fully between pushes. Do not stop until help arrives or an AED is ready.
• A rhythm you can use is the beat of the song "Stayin' Alive."
• An AED (automated external defibrillator) is a device that can shock the heart back into a normal rhythm. Turn it on and follow the voice instructions. It is safe for untrained people to use.
• Early CPR and an AED greatly improve survival. Take a certified CPR course to learn the full skills.
