胸管系統中，下列哪項評估發現代表系統運作正常？
Which assessment finding in a patient with a chest tube indicates that the system is working properly?
- AConstant bubbling in the water seal chamber水封瓶內持續冒泡
- BBubbling in the suction control chamber抽吸控制瓶內冒泡
- CFluctuation (tidaling) in the water seal chamber✓ 正解水封瓶內出現波動（潮汐現象）
- DNo drainage in the collection chamber收集瓶內無引流液
— Explanation · 中文詳解 —
胸管水封瓶（Water seal chamber）若有波動（Tidaling），代表胸腔壓力隨呼吸改變，胸管通暢且未被阻塞。Constant bubbling 暗示漏氣；Suction control chamber 的冒泡則是正常抽吸狀況，但不能與水封瓶混淆。
In a chest tube system, fluctuation (tidaling) in the water seal chamber indicates that intrathoracic pressure varies with breathing, meaning the tube is patent and unobstructed. Continuous bubbling suggests an air leak; bubbling in the suction control chamber is a normal sign of suction function, but it should not be confused with findings in the water seal chamber.
✦ 台美臨床差異
美台皆嚴格監測胸管波動，但美國護理師常受過更嚴謹的胸管系統故障排除訓練（Troubleshooting）。
