Recent developments in pulmonary edema.
Research on lung fluid balance and pulmonary edema has increased during the last decade. New approaches have led to insights into the role of each component of the alveolar-capillary barrier. The capillary endothelium is the first line of defense against lung fluid accumulation. The interstitium may play a more important role in lung fluid balance than previously appreciated. Active and passive transport properties of alveolar epithelium may be important in the pathogenesis and resolution of alveolar edema. New methods for the determination of epithelial permeability and lung water are being evaluated. The developments reviewed here may have an impact on the institution of new diagnostic and therapeutic approaches to pulmonary edema during the next decade.
