What is the procedure called that involves providing oxygen and chest compressions to a victim whose heart has stopped beating?

The procedure that involves providing oxygen and chest compressions to a victim whose heart has stopped beating is known as cardiopulmonary resuscitation, commonly abbreviated as CPR. This emergency lifesaving technique is critical in situations where someone's breathing or heartbeat has stopped, such as in cardiac arrest. CPR aims to restore blood flow to the heart and brain, maintaining vital functions until professional medical help arrives.

The technique consists of two main components: chest compressions, which help circulate blood, and rescue breaths, which provide oxygen to the lungs. The combination of these actions ensures that necessary oxygen reaches the brain and other vital organs, increasing the chances of survival and reducing the risk of permanent damage.

While first aid encompasses a broader range of immediate care measures given in medical emergencies, and emergency response refers to coordinated efforts in managing a crisis situation, neither specifically describes the targeted actions involved in reviving someone whose heart has stopped. Heart resuscitation is not the standard term used in medical communities, making cardiopulmonary resuscitation the correct and proper terminology for this procedure.
