- Call 911
Either call 911 yourself or direct someone else to do it. Make sure whoever calls 911 asks for an ambulance to respond for a collapsed victim. If the 911 dispatcher is able to give directions, ignore this and follow the directions given by the dispatcher.
- Push on the chest
Put the heel of your hand directly on the center of the chest, between the nipples. Push down about 1.5 inches at a rate of 100/minute or about 2 per second.
- These guidelines are meant for untrained rescuers. Trained rescuers may also use these steps for witnessed cardiac arrest.
