CPR (cardiopulmonary resuscitation) is pushing down on a person's chest and breathing into their mouth. It's used in emergencies when someone's heart stops beating or when someone is not breathing normally (may be gasping for breath) or is not breathing at all.
Most children never need rescue breathing or CPR. But if they do, the best thing you can do is be prepared. Talk to your doctor or take a class to learn how to do rescue breathing and CPR, and then use these instructions as a reference.
Automated external defibrillators (AEDs) are in many public places. Before you use an AED, follow all the steps for CPR.
To use an AED, place it next to the child and turn it on. The AED will tell you what to do next.
