— Explanation · 中文詳解 —
胸管（Chest tube）系統的水封瓶（Water seal chamber）若出現持續性冒泡（Constant bubbling），代表胸腔系統存在空氣洩漏（Air leak）。正常情況下，胸管應隨呼吸出現間歇性波動（Tidaling），若有氣胸則會有間歇性冒泡，但持續性冒泡通常代表系統連接口鬆脫、瓶身裂痕或胸管破損。護理師應立即檢查管路氣密性，並通知醫療團隊，嚴禁隨意夾住胸管，以免導致張力性氣胸（Tension pneumothorax）。
Constant bubbling in the water seal chamber indicates an air leak within the chest tube system, which may result from loose connections, a cracked bottle, or a damaged tube. Unlike intermittent bubbling seen during expiration in pneumothorax, continuous bubbling requires immediate assessment of system integrity and notification of the healthcare provider.
