胸管引流病人出現哪種評估結果，顯示可能有氣體洩漏？
Which assessment finding in a client with a chest tube indicates a potential air leak?
- AContinuous bubbling in the water seal chamber✓ 正解水封瓶持續冒泡
- BFluctuation of fluid in the water seal chamber水封瓶內液面波動
- CAbsence of bubbling in the suction control chamber抽吸控制瓶無冒泡
- DIncreased drainage of serosanguineous fluid漿液血性引流液增加
— Explanation · 中文詳解 —
水封瓶的密封水柱中出現「持續性」氣泡（continuous bubbling）通常代表系統存在氣體洩漏（air leak）。週期性波動（fluctuation/tidaling）則是正常呼吸現象。若波動消失，則可能代表肺部已完全復張或引流管阻塞。
Continuous bubbling in the water-seal chamber suggests air leak in the system. Tidaling (fluid fluctuation with respiration) is normal. Absence of tidaling may indicate full lung re-expansion or tube obstruction.
✦ 台美臨床差異
美國護理師常自行使用夾具測試漏氣點；台灣護理師通常需醫師評估後再介入。
