While the chest tube is connected to wall suction, constant bubbling is noted in the water seal chamber indicating an air leak when there is no actual air leak present.When the chest tube is removed from suction (placed to waterseal), the constant bubbling subsides and normal tidaling can be observed indicating there is not an air leak.This was observed on an atrium that was newly changed.The concern is if there is an issue with the internal pressure regulation of the atrium itself and with t he ball being too low in the waterseal chamber/not floating properly.
