Which finding specifically denotes an intermittent air leak?

• A. No bubbling indicates no leak
• B. Continuous bubbling indicates a leak
• C. Bubbling from left to right
• D. Intermittent bubbling with gentle float ball oscillation

Answer: (D)

In chest tube drainage, the pattern of bubbling in the water-seal chamber reveals air leaks. A leak that comes and goes shows up as intermittent bubbling, and the float ball in the chamber will gently oscillate as air enters in bursts. This is the telltale sign of an intermittent air leak. Continuous bubbling means a persistent leak, while no bubbling suggests little or no leak. Bubbling with a directional drift like left to right isn’t a standard indicator. So the finding of intermittent bubbling with gentle float-ball movement best signifies an intermittent air leak.
