What does CPR stand for?

The term CPR is an acronym for Cardiopulmonary Resuscitation. This practice is a critical life-saving technique used when someone has stopped breathing or their heart has stopped beating. The process involves a combination of chest compressions and rescue breaths to restore oxygen flow to the brain and other vital organs, essentially functioning as an artificial method of maintaining circulation and breathing until professional medical help arrives.

Understanding the components of CPR is essential for anyone trained in emergency medical response, as it emphasizes the immediate actions one can take to help sustain life in an emergency situation. This is why the correct answer highlights both the "cardio" aspect related to the heart and "pulmonary" which relates to the lungs, providing clarity on the life-supporting functions it aims to restore.
