Cardiopulmonary resuscitation (CPR) is an emergency procedure that is performed on people who are suffering from cardiac arrest. The purpose of CPR is to provide a flow of oxygenated blood to the brain until other procedures can be performed to restore the person's heartbeat and breathing.
Steps of CPR. CPR (cardiopulmonary resuscitation) is pushing down on a person's chest and breathing into his or her mouth. It is used in emergencies when someone's heart stops beating, or when he or she is not breathing normally (may be gasping for breath) or is not breathing at all. CPR works to move blood to the person's brain to help prevent brain damage. CPR can help keep someone alive until a health professional arrives.
