What does the 'P' in CPR stand for?

The 'P' in CPR stands for "Pulmonary," which relates to the lungs and breathing. CPR stands for Cardiopulmonary Resuscitation, indicating the two critical components involved in the procedure: "Cardio" refers to the heart, while "Pulmonary" refers to the lungs. The process of CPR involves a combination of chest compressions and rescue breaths, aimed at restoring blood circulation and oxygenation to the brain and other vital organs during medical emergencies, such as cardiac arrest.

Understanding the terminology is integral to grasping the steps of CPR, as it highlights the importance of maintaining both heart and lung function to sustain life until professional help arrives.
