What does CPR stand for?

Cardiopulmonary Resuscitation, or CPR, is a life-saving technique used in emergencies when someone's heartbeat or breathing has stopped. The term clearly describes the critical functions it aims to restore: "cardio" refers to the heart, and "pulmonary" pertains to the lungs. When an individual experiences cardiac arrest, performing CPR helps to maintain blood flow to vital organs, especially the brain, until advanced medical help arrives.

Understanding CPR's full name is essential for lifeguards and other first responders, as it reflects the procedure's purpose and reinforces its importance in resuscitation efforts. The other options do not accurately capture the correct terminology used in emergency medical responses, which may lead to confusion or misinformation regarding lifesaving practices.
