Physical examination will detect evidence of atelectasis or pneumonia within the chest . 体格检查可发现胸部有肺不张和肺炎。
2.
Decreased breath sounds may be noted with a pleural effusion , copd , atelectasis and pneumothorax 呼吸音减低则可以在胸腔积液、慢性阻塞性肺病( copd ) 、肺不张和气胸时被发现。
3.
In those ears with complete atelectasis of the middle ear space , staged operation is not indicated 中耳腔完全愈著塌陷之胆脂瘤耳，不适合施行阶段性手术，宜以开放式小中耳腔鼓室成形术为之。
4.
In this case , blood filled the pleural cavity ( hemothorax ) , but atelectasis could also result from filling the chest with air ( pneumothorax ) , transudate ( hydrothorax ) , lymph ( chylothorax ) , or purulent exudate ( empyema ) 但是肺不张也可由胸腔内充满气体（气胸） 、漏出液（胸水） 、淋巴(乳糜胸) ，或者脓性渗出物（脓胸）引起。
5.
A number of conditions causing inadequate entilation ( airway obstruction , pneumonia atelectasis , pleural effusion , and hypoentilation due to the pain of abdominal incisions or to abdominal distention limiting diaphragmatic excursion ) may exist singly or in combination to produce respiratory acidosis 许多导致通气不足的病变（呼吸道梗阻，肺炎性肺不张，胸腔积液，腹部切口疼痛或者腹胀限制了膈肌的运动等引起的低通气）可以单独存在，也可以合并与其它病变而导致呼吸性酸中毒。
