Auto-PEEP and Electromechanical Dissociation

Abstract

Cardiac arrest associated with pulseless electrical activity or electromechanical dissociation carries a poor prognosis unless a reversible cause is recognized and treated promptly. Reversible causes that are traditionally considered include hypovolemia, cardiac tamponade, tension pneumothorax, massive pulmonary embolism, and major metabolic imbalances.¹
