What does the acronym CPR stand for?

The acronym CPR stands for Cardiopulmonary Resuscitation. This term reflects the two critical components of the procedure: "cardio," which refers to the heart, and "pulmonary," which pertains to the lungs. CPR is a life-saving technique used in emergencies when someone's breathing or heartbeat has stopped, allowing oxygen to flow to the brain and other vital organs. Performing this technique effectively can significantly increase the chances of survival until more advanced medical help can be provided.

The other options, while sounding plausible, do not accurately describe the widely accepted definition or purpose of CPR in emergency response. Understanding this abbreviation is fundamental for anyone involved in first aid and emergency situations.
