What is the definition of CPR?

CPR stands for Cardiopulmonary Resuscitation, which is a life-saving technique used in emergencies when someone's heartbeat or breathing has stopped. The technique involves a combination of chest compressions and rescue breaths to maintain blood flow to the brain and other vital organs until professional medical help can arrive. The term "cardiopulmonary" refers to the heart (cardio) and lungs (pulmonary), highlighting the primary functions that CPR aims to restore—oxygenating the body and maintaining circulation.

Understanding this definition is crucial for lifeguards and others trained in emergency response because it encapsulates the goal of CPR: to preserve life by supporting the circulatory and respiratory systems until more advanced medical intervention can be provided. This knowledge is integral to effectively performing CPR in critical situations and recognizing the importance of acting quickly to maximize the chances of survival for a victim of cardiac arrest or respiratory failure.
