一位接有胸管抽吸裝置的病人，下列哪項觀察結果是正常的且預期的？
A nurse is caring for a client with a chest tube connected to a suction device. Which of the following findings is normal and expected?
- ABright red drainage of 300 mL in the last hour最後一小時內有 300 mL 的鮮紅引流液
- BAbsence of any drainage in the collection chamber收集腔室中沒有任何引流液
- CFluctuation of the fluid level in the water seal chamber with respiration✓ 正解水封腔室中的液面隨呼吸波動
- DContinuous bubbling in the water seal chamber水封腔室中有連續冒泡
— Explanation · 中文詳解 —
胸管水封瓶（water seal）內的液體隨呼吸上下波動（tidaling）是正常的生理表現，代表胸腔內壓與呼吸循環同步。持續性氣泡通常暗示漏氣（air leak），大量鮮血代表出血活動，無排水則可能阻塞。
Fluctuation of the fluid level in the water seal chamber, known as tidaling, is a normal finding that reflects pressure changes in the pleural space during respiration. Continuous bubbling indicates an air leak, bright red drainage suggests active hemorrhage, and absence of drainage may signal a blockage in the tubing.
✦ 台美臨床差異
台美胸管照護原則一致，皆重視水封管的水面波動與氣泡監測，強調安全性指標。
