一位使用胸管引流的病人，下列哪些發現顯示引流系統運作正常？（選所有適合的）
A nurse is caring for a client with a chest tube. Which findings indicate the system is functioning correctly? (Select all that apply.)
- AFluctuation of fluid in the water seal chamber with respiration✓ 正解水封瓶內的液體隨呼吸波動
- BContinuous bubbling in the water seal chamber水封瓶內持續冒泡
- CGentle bubbling in the suction control chamber✓ 正解抽吸控制室內輕微冒泡
- DDrainage in the collection chamber is dark red收集瓶內的引流液呈暗紅色
- EThe water level in the water seal chamber rises with inspiration水封瓶內的水位在吸氣時上升

胸管系統運作正常指標：水封瓶隨呼吸出現波動（A）。抽吸室有柔和氣泡表示壓力控制正常（C）。B 選項持續氣泡代表系統漏氣。D 若為鮮紅色且量大才需警覺。E 選項敘述方向錯誤，正常應隨吸氣上升、呼氣下降。
Proper functioning of a chest tube system is indicated by tidaling, where fluid in the water seal chamber fluctuates with respiration, confirming patency. Gentle, continuous bubbling in the suction control chamber also indicates that the prescribed suction pressure is being maintained effectively without excessive force.
✦ 台美臨床差異
台美臨床皆重視引流瓶管理，但美國醫院廣泛使用乾式抽吸系統（Dry-suction），台灣則多見濕式系統。
