The purpose of CPR is to keep oxygenated blood flowing around the body to keep the vital organs alive. CPR itself will not restart someoneâs heart, it just keeps them alive until a defibrillator arrives. A defibrillator is a device which delivers an electrical shock to the heart to restart it.
The main reason to provide CPR is to restore the flow of oxygenated blood to the brain of a victim who has suffered sudden cardiac arrest (SCA). After SCA, the victim is not breathing (or not breathing adequately) and the heart is not pumping oxygenated blood to the brain or vital organs. Clinically the victim is dead.
