This document provides instructions for performing basic life support cardiopulmonary resuscitation (CPR) with two rescuers. It outlines the learning objectives and describes the steps of CPR using the acronym DRABC: Danger, Responsiveness, Airway, Breathing, and Circulation. The roles of each rescuer are defined for assessing the scene, checking responsiveness, opening the airway, giving rescue breaths, and performing chest compressions in a cycle of compressions and ventilations. Potential injuries from CPR like rib fractures and complications like vomiting are also listed.
