胸管引流病人出現何種評估結果，顯示肺部已重新擴張？
Which assessment finding in a client with a chest tube indicates that the lung has re-expanded?
- AContinuous bubbling in the suction control chamber吸引控制室持續冒泡
- BIncreased bloody drainage in the collection chamber收集室中血性引流增加
- CFluctuation of the fluid level in the water seal chamber水封瓶內液面波動
- DAbsence of fluctuation in the water seal chamber✓ 正解水封瓶內無液面波動
— Explanation · 中文詳解 —
水封瓶的波動（Tidaling）反映胸膜腔內壓力隨呼吸改變。當波動停止，代表胸膜腔與外界壓力已平衡，肺部重新擴張貼附於胸壁。A 代表持續漏氣，C 為正常呼吸波動，B 與肺復張無直接因果關係，需進一步評估出血量是否過多。
Tidaling (fluctuation) in the water seal chamber reflects pleural pressure changes with respiration. Cessation of fluctuation indicates that pleural and atmospheric pressures have equalized, signifying that the lung has re-expanded and is adherent to the chest wall. A indicates a continuous air leak, C is normal respiratory variation, and B has no direct relation to lung re-expansion and requires further evaluation for excessive bleeding.
✦ 台美臨床差異
台灣胸腔外科病房常規由護理師觀察波動，美國則可能結合即時 X 光確認，兩者皆需先排除管路扭曲阻塞。
