成人呼吸窘迫综合征(Adult Respiratory Distress Syndrome,简称ARDS)过去称为休克肺、创伤后肺功能不全、创伤性湿肺等,可由内外科多种原因引起。临床表现以进行性呼吸窘迫、过度通气和缺氧为特征。缺氧主要为肺内分流所致,故给氧不能使其氧分压正常升高,死亡率颇高。第二次世界大战期间开始对此综合征有所认识。由于医疗水平和抢救技术的不断提高, Adult respiratory distress syndrome (ARDS), formerly known as shock lung, post-traumatic lung insufficiency, traumatic wet lung, etc., can be caused by a variety of reasons, surgery and surgery. Clinical manifestations are characterized by progressive respiratory distress, hyperventilation and hypoxia. Hypoxia is mainly due to pulmonary shunt, so oxygen can not make its normal partial pressure of oxygen increased, the mortality rate is high. During the Second World War began to recognize the syndrome. Due to the continuous improvement of medical treatment and rescue technologies,
