SUMMARY The pathogenesis of clinical pulmonary edema is considered in the light of recent physiologic and anatomic insights. Pulmonary edema is depicted as a persistent imbalance between the forces that move water into the extravascular spaces and the biologic devices for its removal. In the normal lung, intricate anatomic arrangements coupled with elaborate physiologic mechanisms maintain the ...
Noncardiogenic pulmonary edema, and, to a lesser extent, acute respiratory distress syndrome (ARDS), are common clinical manifestations of drug-induced lung diseases. Clinical features and radiographic appearances are generally indistinguishable from other causes of pulmonary edema and ARDS. Typical manifestations include dyspnea, chest discomfort, tachypnea, and hypoxemia. Chest radiographs co...
BACKGROUND Pulmonary hypertension is a hallmark of high-altitude pulmonary edema and may contribute to its pathogenesis. Cardiovascular adjustments to hypoxia are mediated, at least in part, by the sympathetic nervous system, and sympathetic activation promotes pulmonary vasoconstriction and alveolar fluid flooding in experimental animals. METHODS AND RESULTS We measured sympathetic nerve act...
