Adult respiratory distress syndrome.

Adult respiratory distress syndrome is a type of acute respiratory insufficiency which is preceded by a variety of serious illnesses. The radiologic appearance ranges from scattered densities early in the course to complete consolidation later. Protein and water leak into the interstitium and alveoli. There is right-to-left circulatory shunting with profound hypoxia. Treatment generally includes intubation, suctioning, oxygen and mechanical ventilation with positive end-expiratory pressure. Diuretics and methylprednisolone may also be used.
