胸管系統中，哪項評估結果顯示系統運作正常？
Which assessment finding in a client with a chest tube indicates that the system is working properly?
- AAbsence of drainage in the collection chamber收集室中無引流液
- BBubbling in the suction control chamber抽吸引流控制室中有氣泡
- CFluctuation of the fluid in the water seal chamber with respirations✓ 正解水封室中的液體隨呼吸波動
- DContinuous bubbling in the water seal chamber水封室中持續有氣泡
— Explanation · 中文詳解 —
水封瓶的液面隨呼吸波動（Tidaling）是胸膜腔與系統相通的正常表現。若波動停止，可能代表胸管阻塞或肺部已擴張。連續氣泡（Continuous bubbling）通常代表系統有漏氣，而抽吸控制室（Suction control chamber）中有氣泡則代表有啟動負壓，但 Tidaling 是觀察胸管暢通的核心標準。
Tidaling — fluctuation of the fluid level in the water-seal chamber with respirations — indicates normal communication between the pleural space and the system. If tidaling stops, the chest tube may be obstructed or the lung may have re-expanded. Continuous bubbling typically signals a system air leak, while bubbling in the suction control chamber simply indicates active suction; tidaling, however, is the core indicator that the chest tube is patent.
