Observe the water seal for intermittent bubbling from its U tube or for a rise and fall of fluid that is synchronous with respirations.(For example,in a nonmechanically ventilated patient,the fluid rises during inspiration,and the fluid level falls during expiration.When a patient is on a mechanical ventilator,the opposite occurs. )In a nonmechanically ventilated patient,the fluid rises during inspiration,and the fluid level falls during expiration.Constant bubbling in the water seal or a sudden,unexpected stoppage of water-seal activity is considered abnormal and requires immediate attention.After 2 to 3 days,tidaling or bubbling on expiration is expected to stop,indicating that the lung has reexpanded.
