Acute alveolar edema.

The interrelationships of several important factors contribute to the development of pulmonary edema. These factors include hydrostatic and osmotic forces, capillary membrane permeability, and lymphatic drainage capacity. Whether the pulmonary edema is cardiogenic or noncardiogenic, optimal management is facilitated by the improvement of ventilation and gas exchange within the lungs and the restoration of oxygen transport to peripheral tissues. The keystones in such therapy include the administration of oxygen, diuretics, and vasodilators; the use of mechanical ventilation; and the implementation of specific therapy directed toward underlying disorders.
