護理師照護一位使用封閉式胸腔引流系統的病人，下列何者顯示該系統運作正常？
A nurse is caring for a client with a chest tube connected to a closed-chest drainage system. Which finding indicates the system is functioning correctly?
- AContinuous bubbling in the water seal chamber水封瓶內持續冒泡
- BAbsence of drainage in the collection chamber收集瓶內無引流液
- CFluctuation of the fluid level in the water seal chamber✓ 正解水封瓶內液面隨呼吸波動
- DBubbling in the suction control chamber when suction is off關閉吸引時吸引控制瓶內冒泡
— Explanation · 中文詳解 —
胸腔引流管的水封瓶液面隨病人呼吸波動（潮汐現象）代表引流管通暢且胸膜腔壓力正確傳導。持續氣泡（A）通常代表系統有漏氣；完全無引流可能與引流管阻塞相關； suction chamber 應僅在連接吸引器時產生氣泡。
Fluctuation of the fluid level in the water seal chamber, known as tidaling, indicates that the chest tube is patent and responding to normal intrathoracic pressure changes. Continuous bubbling suggests an air leak, while absence of fluctuation may indicate obstruction.
✦ 台美臨床差異
台美胸管照護原則一致，但美國護理師常執行移除胸管前之夾管觀察，台灣多由醫師執行。
