CPR is important
CPR can keep oxygenated blood flowing to the brain and other vital organs until more definitive medical treatment can restore a normal heart rhythm. When the heart stops, the lack of oxygenated blood can cause brain damage in only a few minutes.
Definition
Cardiopulmonary resuscitation, or CPR, is a procedure in which you basically try to restart someone’s breathing or heart by manually compressing the person’s chest and pushing air into the lungs by breathing into the person’s mouth.
