"CPR" is an acronym for cardiopulmonary resuscitation, which is a life-saving technique that is sometimes able to help restore a heartbeat or breathing in someone who is experiencing a life-threatening emergency. CPR involves restoring blood circulation, clearing the airway if necessary, and breathing for a person unable to breathe.
The American Heart Association recommends that CPR always should begin with chest compressions. The method used to perform CPR varies slightly depending on the person receiving the life-saving technique. When performing CPR on a child, only one hand should be used when performing chest compressions. For a baby, only two fingers should be used.
