胸管系統中，哪項評估發現顯示系統運作正常？
Which assessment finding in a client with a chest tube indicates that the system is functioning correctly?
- AFluctuation of fluid in the water seal chamber with respiration✓ 正解水封瓶內液面隨呼吸起伏
- BAbsence of drainage in the collection chamber集液瓶無引流物
- CSubcutaneous emphysema around the insertion site置管處周圍有皮下氣腫
- DContinuous bubbling in the water seal chamber水封瓶內持續冒泡
— Explanation · 中文詳解 —
胸管水封瓶（water seal chamber）的液面隨呼吸起伏（tidaling）是正常的呼吸力學反應，表示胸腔內壓力與系統相通。持續性氣泡通常代表漏氣；無引流物可能正常但非系統功能指標；皮下氣腫則為異常併發症。
Fluctuation of fluid in the water seal chamber with respiration, known as tidaling, indicates that the chest tube system is patent and functioning correctly. Continuous bubbling suggests an air leak, while subcutaneous emphysema indicates a complication rather than proper system function.
✦ 台美臨床差異
美台臨床皆高度重視胸管護理，但美國在氣胸護理師授權範疇下，對於判定 air leak 的標準有嚴格的教學一致性。
