自发性气胸是阻塞性肺气肿的常见并发症。原已损害的肺功能由于气胸机械性压迫肺脏和肺循环,极易诱发生理功能衰竭,所以也是肺科的常见急诊之一。这类病的发病初始,气胸可能限于一侧。由于呼吸功能负担剧增,呼吸困难和缺氧加重,支气管痉挛,使对侧气道阻力也进一步增加,肺泡气阻滞,导致肺泡破 Spontaneous pneumothorax is a common complication of obstructive pulmonary emphysema. Lung function has been impaired due to pneumothorax mechanical compression of the lungs and pulmonary circulation, easily induced physiological failure, it is also one of the most common pulmonary emergency. The onset of such diseases, pneumothorax may be limited to one side. Due to the surge in respiratory function burden, dyspnea and hypoxia increased, bronchospasm, the contralateral airway resistance also increased further, alveolar gas block, leading to alveolar rupture
