Cardiopulmonary resuscitation (CPR) is a key part of emergency medical care designed to resuscitate individuals in cardiac arrest. The purpose of cardiopulmonary resuscitation is to temporarily provide effective oxygenation of vital organs, especially the brain and heart, through artificial circulation of oxygenated blood until the restoration of normal cardiac and respiratory activity occurs. This is to stop the degenerative processes of ischemia and anoxia caused by inadequate circulation and inadequate oxygenation. Time to initiation of cardiopulmonary resuscitation is critical to improve likelihood of recovery; ideally, it should be started within 4 min of arrest, and advanced cardiac life support should be initiated within 8 min of arrest. While basic life support alone may be lifesaving in some instances, in most cases, advanced interventions such as the delivery of electric current for defibrillation and the addition of various pharmacologic therapies are required to maximize the likelihood of patient recovery. Without rhythm-specific interventions, recovery from cardiac arrest is highly unlikely.
This chapter reviews basic CPR for adults, including approach to an unresponsive patient, basic airway opening procedures including initial management of an obstructed airway, and the physiology and mechanics of closed-chest compression techniques.
