CPR (Cardiopulmonary Resuscitation)

Cardiopulmonary resuscitation (CPR) is a lifesaving technique used during emergencies when someone's heart stops beating or they stop breathing. It combines chest compressions and rescue breaths to help maintain blood flow and oxygen to vital organs. The primary actions involve pushing down hard and fast in the center of the chest to mimic the heart's pumping action, and if trained, giving breaths to provide oxygen. CPR can keep a person alive until professional help arrives, and knowing how to perform it can significantly increase their chances of survival during cardiac emergencies.
