Shock is a life-threatening condition of circulatory failure that causes an imbalance between cellular oxygen supply and demand resulting in organ dysfunction. It is important to recognize promptly as it is reversible in earlier stages but will transition to an irreversible phase if left untreated. This will result in multiorgan failure and subsequent death. The clinician should therefore consider shock in the differential for all patients with new organ failure. This article will review the pathophysiology, classification, evaluation, and management of shock.
