Continuous bubbling in the air leak monitor indicates what?

• A. No air leak
• B. The patient has improved
• C. The bottle is full
• D. Air leak in the system

Answer: (D)

Continuous bubbling in the air leak monitor means there is an ongoing air leak somewhere in the chest drainage system or from the pleural space. In a chest-tube setup, a little bubbling during exhalation is normal, but persistent bubbling indicates air is continually escaping rather than being fully resolved. This points to a leak in the system or in the lung, such as a loose connection, a puncture in the tubing, or residual air from the injured area. It’s not a sign of improvement, and it’s not simply because the bottle is full. The appropriate step is to check all connections and tubing for kinks, disconnections, or cracks, verify the suction settings, and notify the healthcare team if the bubbling persists or there are signs of patient distress.
