What does CPR stand for?

CPR stands for Cardiopulmonary Resuscitation. This term accurately describes the two critical life-saving functions that CPR aims to restore: circulation and breathing. "Cardio-" refers to the heart, while "pulmonary" pertains to the lungs. By performing CPR, a responder provides artificial ventilation and chest compressions to maintain blood flow and oxygenation in an individual who has stopped breathing or whose heart has stopped beating.

Understanding the full term is vital for first responders, as it encompasses the fundamental processes employed to revive someone experiencing cardiac arrest or respiratory failure, thereby drastically improving their chances of survival and recovery. The other options, while they may seem plausible, do not reflect the established terminology and practices within emergency medical response.
