過度動態性呼吸道塌陷起因於氣管與支氣管後壁於吐氣時期過度地朝管腔內凹陷；其臨床表現不易和其它阻塞性肺病區分，但致病機轉與治療卻不相同，然若非藉由適當之影像學檢查不易診斷，長期則可能導致患者反覆呼吸道感染甚至慢性呼吸衰竭。本文針對此病症回顧現有相關文獻，作一概括性介紹，期能加深讀者對此一近來漸受重視的呼吸道病變之認識。

Excessive dynamic airway collapse results from the overt invagination of the posterior tracheo-bronchial wall during tidal expiration. Its clinical presentations are not easily distinguishable from other common obstructive airway disorders, while the therapeutic principles are distinct. Diagnosis requires appropriate imaging studies.Long term sequelae of the disorder include recurrent lower airway infection and even chronic respiratory failure.By reviewing the current relevant literature, this article attempts to acquaint the readers with such an airway disorder that has gained growing attention in recent years.
