What is the primary purpose of CPR?

The primary purpose of CPR, or cardiopulmonary resuscitation, is to restore breathing and circulation in a person who has stopped breathing or whose heart has stopped beating. This life-saving technique aims to maintain vital blood flow to the brain and other essential organs until professional medical help arrives. When performed correctly, CPR can significantly increase the chances of survival and minimize the likelihood of irreversible brain damage caused by a lack of oxygen.

The other choices focus on different aspects of emergency response but do not directly address the critical role of CPR. Stopping blood flow is not a goal, and while comfort might be important in providing care, it is secondary to the immediate need to revive the victim. Additionally, preparing a victim for medical transport is a part of the overall emergency response process, but it is not the primary objective of administering CPR itself.
