What does continuous bubbling in a chest tube drainage indicate?

• A. Air leak in the chest tube system
• B. Obstruction by clot
• C. Water seal disrupted
• D. No drainage

Answer: (A)

Continuous bubbling in chest tube drainage means there is an ongoing air leak in the chest tube system. Air from the pleural space is escaping through the tubing into the drainage apparatus, so bubbles keep forming in the water-seal (or suction) chamber regardless of breath. This pattern points to a leak somewhere in the circuit—such as a loose connection, a puncture in the tubing, or a leak at the chest insertion site. It’s different from an obstruction by a clot, which would reduce or stop drainage and not produce continuous bubbling. If this bubbling persists, check and secure all connections, ensure the system is below chest level and free of kinks, and consult the clinician if the leak remains large or the patient deteriorates.
