成人呼吸窘迫综合征(ARDS)系非心原性肺水肿引起的急性呼吸衰竭,乃是休克、败血症、战伤、车祸、病毒性呼吸道感染,以及许多其它损害的一种复杂结局。并且尽管给予先进的支持疗法,但仍有半数病例终归死亡。ARDS现代观念的进展早期学者认为,本病的发生机理与新生儿呼吸窘迫综合征及心源性肺水肿相似。Petty等推测,ARDS可能起因于表面活性物质合成 ARDS is a complex outcome of non-cardiogenic pulmonary edema caused by acute respiratory failure but is shock, septicemia, war injuries, car accidents, viral respiratory infections, and many other injuries. And despite giving advanced supportive care, half of all cases are still dead. Advances in the modern concept of ARDS Early scholars believe that the pathogenesis of this disease is similar to neonatal respiratory distress syndrome and cardiogenic pulmonary edema. Petty et al hypothesize that ARDS may result from surfactant synthesis
