What is the meaning of CPR in emergency medicine?

CPR stands for Cardiopulmonary Resuscitation, which is a life-saving technique used in emergencies when someone's breathing or heartbeat has stopped. Understanding this term is crucial in emergency medicine, as it combines chest compressions and rescue breaths to maintain blood flow and oxygen delivery to the brain and other vital organs. This intervention is particularly effective during cardiac arrest, where immediate action can significantly increase the chances of survival and recovery. Knowledge of CPR is essential for healthcare providers and laypersons alike, enabling them to respond promptly to such critical situations. The other options presented, while they may seem plausible, do not accurately reflect the widely accepted terminology used in medical practice.
