What does the acronym "CPR" stand for in first aid?

The acronym "CPR" stands for Cardiopulmonary Resuscitation, which is a critical emergency procedure used in life-threatening situations when someone's heart has stopped beating or they are not breathing. CPR combines chest compressions and rescue breaths to maintain circulation and oxygenation of vital organs until professional medical help arrives.

Understanding the concept of CPR is crucial for anyone involved in first aid, as it is a life-saving technique that can significantly increase the chances of survival following cardiac arrest. The other choices do not accurately represent the standardized term used in first aid and emergency response training. For instance, Cardiovascular pressure response and Cervical pulse regulation do not delineate the essential components of CPR, while Cardiac primary rescue, though it hints at emergency response, does not encompass the comprehensive nature of both the cardiac and pulmonary aspects that are critical to the resuscitation process.
