What does CPR stand for?

CPR stands for Cardiopulmonary Resuscitation, which is a life-saving procedure performed when someone's breathing or heartbeat has stopped. The term "cardiopulmonary" refers to the heart (cardio) and lungs (pulmonary), indicating the two critical systems involved in the procedure. CPR combines chest compressions to restore blood circulation and rescue breaths to provide oxygen to the lungs. This technique is essential in medical emergencies such as cardiac arrest, where prompt action can significantly improve the chances of survival and recovery.

The other options, while they may sound plausible, do not accurately describe the procedure of CPR or its intended purpose in emergency situations. Understanding what CPR stands for is crucial for anyone trained in first aid, as it highlights the fundamental role this procedure plays in emergency response and can help save lives.
