Abstract
The most effective treatment for cardiac arrest is the administration of high-quality chest compressions and early defibrillation; once spontaneous circulation is restored, post–cardiac arrest care is essential to support full return of neurologic function. This review summarizes the pathophysiology, stabilization and assessment, diagnosis and treatment, and disposition and outcomes of cardiac arrest and resuscitation. Figures show the foundations of cardiac resuscitation, ventricular arrhythmias, coronary perfusion pressure as a function of time, an algorithm for initial treatment of cardiac arrest, sample capnographs, and the electrocardiographic appearance of varying degrees of hyperkalemia. Tables include components of suboptimal cardiac resuscitation and corrective actions, recommended doses of medications commonly used in cardiac resuscitation, causes of pulseless electrical activity/asystolic arrest to consider, immediate post–return of spontaneous circulation checklist, and resuscitation goals during post–cardiac arrest care. This review contains 6 highly rendered figures, 5 tables, and 142 references.
