護理師評估一位裝有胸管的病人。發現水封瓶（Water seal chamber）內有持續性氣泡（Continuous bubbling）。此發現代表什麼？
A nurse is assessing a client who has a chest tube. The nurse observes continuous bubbling in the water seal chamber. What does this finding indicate?
- AThe chest tube is properly connected to suction胸腔引流管正確連接至抽吸裝置
- BNormal resolution of a pneumothorax氣胸的正常恢復過程
- CThe client is experiencing a pulmonary embolism病人正在經歷肺栓塞
- DA leak in the chest tube system✓ 正解胸腔引流系統有漏氣
水封瓶應只有在病人咳嗽或呼氣時出現「間歇性」氣泡（表示氣胸正排出空氣）。若出現「持續性」氣泡，代表系統存在漏氣（Air leak），空氣持續進入胸腔或系統管路中。這需要從插入部位沿管路檢查，找出漏氣點並處理，否則會影響胸膜腔負壓建立，導致肺部塌陷。
Continuous bubbling in the water seal chamber indicates an air leak within the chest tube system, rather than normal intermittent bubbling associated with coughing or expiration. This suggests that air is continuously entering the pleural space or the tubing, which compromises the negative pressure needed for lung re-expansion. The nurse should inspect the system for disconnections or leaks and notify the provider promptly.
胸管護理在兩國皆屬高警覺項目，台灣護理師常需在交班時確認水封瓶液面晃動及氣泡狀態，美國則更強調針對潛在氣胸進行系統性排除檢測。
