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.
CPR may be done when a person stops breathing or the heart stops beating (like when a person has a heart attack or almost drowns). When it's possible that the person may get better, CPR is an important life-saving technique.PR may prolong life for patients who have a better health status or who are younger. CPR may also prolong life if it's done within 5 to 10 minutes of when the person's heart stopped beating or breathing stopped.
