護理師照護一位放置胸管的病人，觀察到水封瓶出現持續性氣泡（continuous bubbling）。此現象代表什麼？
A nurse is caring for a client with a chest tube. The nurse observes continuous bubbling in the water seal chamber. What does this indicate?
- AThe chest tube is properly functioning胸管運作正常
- BThe suction is set too high抽吸設定過高
- CThere is an air leak in the system✓ 正解系統中有漏氣
- DThe client is experiencing a pneumothorax resolution病人正在經歷氣胸消退
— Explanation · 中文詳解 —
水封瓶的氣泡反映胸腔內的空氣排出狀況。間歇性氣泡通常隨呼吸動作出現，屬於正常排除空氣的過程。然而，若出現「持續性」氣泡，通常意味著系統連接處不密封，導致空氣持續從外部進入系統，即為漏氣（Air leak），需立即檢查連接處。
Continuous bubbling in the water seal chamber indicates an air leak within the thoracic cavity or the drainage system connections. Unlike intermittent tidaling, which reflects normal respiratory movement, persistent bubbling signifies that air is continuously entering the system from an external source, requiring immediate assessment of all connections.
✦ 台美臨床差異
胸管護理在台美皆重視臨床觀察，美國護理師對胸管系統故障處理（更換引流瓶）的授權度通常較高。
