Shock is a pathophysiological state characterized by inadequate tissue oxygenation due to an imbalance of oxygen delivery and consumption. It is a life-threatening condition that may lead to cellular death and vital organ dysfunction. Shock is a major cause of morbidity and mortality. There are four major categories of shock: cardiogenic, hypovolemic, distributive, and obstructive. Hemodynamic data obtained from intra-arterial pressure monitoring and pulmonary artery catheterization provide additional information to aid in the optimal assessment of shock.
