What does the acronym "CPR" stand for?

The acronym "CPR" stands for Cardiopulmonary Resuscitation. This term refers to a critical emergency procedure performed on individuals whose heart has stopped beating or who are not breathing. It combines chest compressions to maintain blood circulation and rescue breaths to provide oxygen to the lungs.

Understanding the precise terminology in lifesaving techniques like CPR is essential for effective communication in emergency situations. Knowing that "cardio" relates to the heart and "pulmonary" pertains to the lungs helps clarify the purpose of the procedure, which is to restore circulation and breathing until advanced medical help arrives. Other choices do not accurately reflect the established terminology associated with lifesaving medical practices, which makes them less relevant in this context.
