Adult Respiratory Distress(ARDS)是临床常见的综合征,死亡率高,在美国每年有15万人发病,死亡率高达50-76％,我国无精确统计数字,目前由无特异的理想的治疗方法,故深为基础与临床医务人员所关注。尽管其发病原因很多,如休克、创伤、吸入液体、药物过量、有害气体吸入、血液疾病、Dic、代谢紊乱、人工心肺、高浓度O_2等,但其主要的病理生理特点是一致的。 Adult respiratory distress (ARDS) is a common clinical syndrome, high mortality, incidence of 150,000 people each year in the United States, the mortality rate as high as 50-76%, no accurate statistics in our country, currently no specific ideal treatment, Therefore, based on deep and clinical medical staff attention. Although its causes are numerous, such as shock, trauma, fluid ingestion, overdose, inhalation of noxious gases, blood diseases, Dic, metabolic disorders, artificial heart and lungs, high concentrations of O 2, etc., its main pathophysiological characteristics are consistent.
