This document provides guidance on performing CPR on an adult victim. It describes the purpose of CPR as maintaining blood flow and oxygen to the brain and heart until more advanced resuscitation can be attempted. The key steps of CPR are outlined, including checking for responsiveness, opening the airway, providing rescue breaths, and administering chest compressions at a rate of 100 per minute until emergency services arrive or spontaneous circulation returns. Recent guidelines from the American Heart Association are also summarized, such as compressing at least 2 inches deep and giving 30 compressions followed by 2 breaths.
