胸管病人的水封瓶腔室（water seal chamber）出現持續性氣泡。這代表什麼意義？
A client with a chest tube has continuous bubbling in the water seal chamber. What does this finding indicate?
- AThe suction pressure is too high抽吸壓力過高
- BThere is an air leak in the system✓ 正解系統存在漏氣
- CThe system is functioning normally系統運作正常
- DThe lung has fully re-expanded肺部已完全復張
— Explanation · 中文詳解 —
水封瓶腔室應僅在呼吸或咳嗽時有間歇性氣泡（Tidaling）。持續性氣泡通常代表系統某處有漏氣（Air leak）。若氣泡是在抽吸腔室（Suction control chamber），則持續氣泡是正常的。此題區分水封腔與抽吸腔非常關鍵。
The water seal chamber should show only intermittent bubbling (tidaling) during respiration or coughing. Continuous bubbling usually indicates an air leak somewhere in the system. If bubbling occurs in the suction control chamber, continuous bubbling is normal. Distinguishing the water seal chamber from the suction chamber is essential.
✦ 台美臨床差異
美國 NCLEX 對胸管護理細節要求極高；台灣臨床護理師亦需具備判斷漏氣位置（病人端或機器端）的能力。
