自发性张力性气胸

定义

当胸腔内压力在整个呼气以及吸气过程中大于大气压时，就会出现张力性气胸。张力性气胸的发病机制是脏层或壁层胸膜破裂，形成单向瓣膜。张力性气胸可发生在任何类型的气胸之后；它与病因无关。有时可发生在自发性气胸后，但更常见于创伤性气胸、机械通气或心肺复苏期间。

A tension pneumothorax is present when the intrapleural pressure is greater than atmospheric throughout expiration and often during inspiration as well. The mechanism responsible for tension pneumothorax is the disruption of the visceral or parietal pleura in such a manner that a one-way valve develops. A tension pneumothorax can occur after any type of pneumothorax; it is independent of the etiology. It can sometimes occur after a spontaneous pneumothorax but is more common after a traumatic pneumothorax, with mechanical ventilation, or during cardiopulmonary resuscitation.
