ARDS急性呼吸窘迫征的簡單概述和臨床表現(xiàn)。

急性呼吸窘迫征來自Tina空中微課堂00:0002:04Acute respiratory distress syndrome （ARDS） occurs when fluid builds up in thetiny, elastic air sacs （alveoli） in your lungs. The fluid keeps your lungs fromfilling with enough air, which means less oxygen reaches your blood stream. Thisdeprives your organs of the oxygen they need to function.

當(dāng)液體積聚在肺部微小的、具有彈性的氣囊（肺泡）中，會發(fā)生急性呼吸窘迫綜合征（ARDS）。積聚的液體阻止肺部充滿足夠的空氣，這意味著更少的氧氣進入血液，這使器官缺少足夠的氧氣以發(fā)揮正常功能。

ARDS typically occurs in people who are already critically ill or who have significant injuries. Severe shortness of breath — the main symptom of ARDS — usually develops within a few hours to a few days after the precipitating [pr?'s?p?te?t??] injury or infection.

ARDS通常發(fā)生在已患有重病或重傷的人群中。嚴(yán)重呼吸窘迫（ARDS的主要癥狀）通常在受傷或感染后幾小時至幾天內(nèi)發(fā)生。

Many people who develop ARDS don't survive. The risk of death increases with age and severity of illness. Of the people who do survive ARDS, some recover completely while others experience lasting damage to their lungs.

許多患ARDS的人會死亡，死亡風(fēng)險隨著年齡和疾病的嚴(yán)重程度而增加。在ARDS存活下來的人群，有些人會完全康復(fù)，而有些人則會出現(xiàn)肺部的持久損傷。
