The adult respiratory distress syndrome (ARDS) is a common syndrome of diffuse lung injury with high mortality. An underlying mechanism is pulmonary microvascular injury leading to increased permeability, pulmonary edema and impaired gas exchange. ⋯ The development of an accurate clinical marker of pulmonary microvascular injury or a technique to measure pulmonary microvascular permeability may allow earlier and more specific diagnosis. We review ARDS with emphasis on recent work concerning the mechanisms of lung injury, diagnosis, and therapy.
