Where should there NOT be continuous bubbling in the chest tube drainage system?

• A. Air leak monitor
• B. Suction control chamber
• C. Water-seal chamber
• D. Collection chamber

Answer: (A)

The chest tube system is designed to remove air and fluid while preventing air from re-entering the chest. A key sign of a problem is continuous bubbling, which typically means an ongoing air leak. In this setup, the air leak monitor is the part that shows whether air is escaping through the system. If you see continuous bubbling in that monitor, it indicates a persistent air leak somewhere along the chest tube pathway. When the system is functioning normally and there isn’t a leak, the air leak monitor should remain relatively quiet. So, there should not be continuous bubbling in the air leak monitor. Bubbling in the suction control chamber is expected when suction is applied, since air is being drawn through to maintain negative pressure. Bubbling in the water-seal chamber is usually minimal and may occur with coughing or exhalation, but continuous bubbling there also signals an abnormal air leak in the chest tube or connections. The collection chamber is for drainage and should not be bubbling as part of normal operation. If continuous bubbling is observed in the air leak monitor, it prompts assessment of the entire system for a leak, disconnections, or a lung air leak that needs attention.
