A
Continuous bubbling in the water-seal chamber with an absence of bubbles in the suction control chamber indicates that there is a leak in the system. Normal functioning is indicated by gentle, continuous bubbling in the suction chamber and occasional bubbling in the water seal, with fluctuations on inspiration and expiration. Constant bubbling in the water seal or a sudden, unexpected stoppage of water-seal activity is considered abnormal and requires immediate attention. Insufficient suction pressure has little to no bubbling in the suction chamber.
