一位病人剛裝上胸腔引流管，護理師觀察到水封瓶（water-seal）有持續氣泡。應懷疑什麼？
A client has a chest tube that was recently inserted. The nurse notices constant bubbling in the water-seal chamber. What should the nurse suspect?
- AThe suction is too low吸力太低。
- BThe tubing is blocked管路阻塞。
- CAn air leak in the system✓ 正解系統中有空氣洩漏。
- DNormal lung re-expansion正常的肺部復張。
— Explanation · 中文詳解 —
水封瓶內的持續性氣泡（Constant bubbling）代表空氣不斷從外部進入系統或從肺部漏出，這是嚴重的漏氣（Air leak）。正常的肺擴張過程中，氣泡應在呼氣時出現，隨著時間減少；若持續冒泡即表示系統不密閉或肺部仍有氣胸。
Continuous bubbling in the water-seal chamber of a chest tube system indicates an air leak within the tubing or from the pleural space. Unlike intermittent bubbling associated with normal lung re-expansion, persistent bubbling suggests the system is not airtight and requires immediate assessment to locate and correct the leak.
✦ 台美臨床差異
美台臨床對胸管監測的觀念相同，均要求護理師定期檢查各連接處密封性。
