A client with a chest tube has continuous bubbling in the water seal chamber. What should the nurse suspect?
- AAn air leak in the chest tube system✓ 正解胸腔引流管系統有漏氣
- BA kink in the drainage tubing引流管路扭結
- CThe suction is turned off吸引裝置已關閉
- DNormal lung re-expansion肺部正常復張

胸腔引流系統的水封瓶（Water seal chamber）功能在於防止空氣回流至胸膜腔。正常情況下，隨呼吸會有波動（Tidaling），若出現連續性氣泡（Continuous bubbling），則強烈暗示系統中有空氣洩漏（Air leak）。這會導致胸膜腔負壓喪失，增加氣胸風險，護理師需立即檢查所有接頭密封性。
Continuous bubbling in the water seal chamber indicates an air leak within the chest tube system, which compromises the negative pressure required for lung re-expansion. While normal tidaling occurs with respiration, persistent bubbling suggests a disconnection or leak that requires immediate assessment of all connections.
