成人呼吸窘迫综合征(ARDS)是一涉及临床各科,以急性进行性呼吸窘迫和难治性低氧血症为主要特征的临床综合征,临床表现凶险,死亡率约在30～50%之间。现对其疗法进行评价:氧疗法与氧中毒严重低氧血症是 ARDS 临床表现的主要特征,亦是危及病人生命的主要因素。因此氧疗是 ARDS 治疗的根本措施之一,但已经证实吸入高浓度氧对机体有严重的毒害作用,一般认为其主要损伤机制为释放大量的
Adult respiratory distress syndrome (ARDS) is a clinical syndrome characterized by acute progressive respiratory distress and refractory hypoxemia, with clinical manifestations and mortality of about 30-50% between. Therapies are now evaluated: Oxygen Therapy and Oxygen Poisoning Serious hypoxemia is a major feature of the clinical presentation of ARDS and is a major factor in endangering patients’ lives. Therefore, oxygen therapy is one of the fundamental measures of ARDS treatment, but has been confirmed by inhalation of high concentrations of oxygen on the body has a serious toxic effects, it is generally believed that the main mechanism of injury is the release of large amounts of
