What is the primary purpose of CPR?

The primary purpose of CPR, or cardiopulmonary resuscitation, is to revive breathing and circulation in a person who has stopped breathing or whose heart has ceased functioning effectively. This life-saving technique works by maintaining blood flow to the brain and other vital organs during a cardiac arrest situation. The chest compressions help to pump blood through the heart and keep oxygen-rich blood circulating, while rescue breaths provide oxygen to the lungs.

Although stabilizing an injury, administering first aid, and preventing blood loss are important aspects of overall emergency response, they do not directly address the critical immediate need created by cardiac arrest. CPR specifically targets the restoration of normal breathing and heart function, making it essential for survival until professional medical help can arrive.
