摘要

一個接受容積控制通氣模式的插管病人發生氣胸，通常其呼吸道峰值壓力與平原壓力會上升。而我們報導一位接受容積控制通氣模式之插管病人，於接受完支氣管鏡檢查後，隨即發生氣胸的早期呼吸力學變化，我們發現於其氣胸發展的早期，呼吸道平原壓力並沒有立即升高，而其平原壓力的衰減是較一般的情形要來得顯著，這些發現或許可以當作是使用呼吸器的病人發生氣胸的早期徵兆。

Pneumothorax that develops in intubated patients under volume-controlled ventilation (VCV) is usually associated with increased peak and plateau airway pressures [1-2]. We report the early evolutional changes in the respiratory mechanics of an intubated patient who developed pneumothorax immediately after a bronchoscopic examination while under volume-controlled ventilation. We found that the patient's airway plateau pressure did not increase in the early developing stage of pneumothorax, and that the decay of the plateau pressure was more pronounced. These findings may give us early warning signs of a developing pneumothorax in mechanically-ventilated patients.
