Over time, trapped air slowly diffuses into the bloodstream, and tiny airways collapse - a process called atelectasis.

随着时间的，一段空气会慢慢扩散到血液中，细小气管萎缩内陷，就是肺的形成过程。

Inflamed airways along with atelectasis and air trapping due to mucus plugs can lead to difficulty breathing and hypoxia.

气管产生炎症，黏液栓导致的肺气体潴留，会导致呼吸困难和缺氧症。

Both atelectasis and air-trapping can sometimes be seen in the different regions of the lungs at the same time like in this chest X-ray.

有时在肺部的同区域，可同时出现肺和气体潴留，就像图中的个胸部X片一样。
