Cardiopulmonary resuscitation

Cardiopulmonary resuscitation or CPR is an emergency measure administered to a person whose heart has stopped beating. A person who has turned unconcious or is not breathing normally can be given cardiopulmonary resuscitation. This involves chest compressions and mouth-to-mouth resuscitation. CPR allows oxygen and blood circulation to a person's heart when it has suffered a cardiac arrest. It allows the brain and other organs to remain alive till the person is taken to a hospital. This delays tissue death and permanent brain damage. CPR can be performed on adults, children and infants.
