Pulmonary edema is a pathologic state in which there is an excessive accumulation of fluid in the extravascular tissues of the lung. It occurs when the balance of factors governing movement of fluid across the alveolar-capillary membrane (hydrostatic and osmotic pressure gradients and the permeability characteristics of the capillary wall, described in Fig. 1) shifts to allow more fluid to be filtered from the pulmonary capillaries than can be removed by vascular reabsorption and lymphatic clearance.
