急性呼吸窘迫综合征亦称成人呼吸窘迫综合征(Acute or Adult respiratory distress Syndrome),简称 ARDS。本症是临床常见的严重并发症,它是一种特殊类型的呼吸功能衰竭,其主要表现是急性进行性呼吸困难和低氧血症。其发生不是由于中枢性呼吸抑制及急性左心衰所致肺水肿,也不是由于慢性肺实质病变。本征死亡率极高,现已成为危重病人抢救的一个重要课题。 Acute or respiratory distress syndrome is also known as Acute or Adult respiratory distress syndrome (ARDS). The disease is a common clinical serious complication, it is a special type of respiratory failure, its main manifestations are acute progressive dyspnea and hypoxemia. Its occurrence is not due to central respiratory depression and pulmonary edema caused by acute left heart failure, nor is it due to chronic pulmonary parenchymal disease. Extremely high mortality rate has become an important issue for the rescue of critically ill patients.
