一位裝置胸管的病人，水封瓶持續冒泡，這指示什麼？
A client with a chest tube has continuous bubbling in the water seal chamber. What does this suggest?
- ANormal lung re-expansion正常的肺部復張
- BNegative pressure is restored已恢復負壓
- CA leak in the system✓ 正解系統有漏氣
- DPleural fluid drainage胸膜腔積液引流

胸管引流系統的水封瓶（Water seal chamber）功能在於防止空氣進入胸腔。若出現「持續性冒泡（Continuous bubbling）」，代表系統中存在空氣洩漏（Air leak）。這可能是管路連接處鬆脫、傷口敷料密封不全，或是肺部存在持續性氣胸。正常情況下，水封瓶應僅隨病人的呼吸出現波動（Tidaling）。
Continuous bubbling in the water seal chamber of a chest tube system indicates an air leak within the tubing or at the insertion site. This differs from intermittent tidaling, which is normal and reflects changes in intrathoracic pressure during respiration. Persistent bubbling requires immediate assessment to locate and repair the leak to restore proper negative pressure.
