How should the vacuum regulator be adjusted after the set-up of a chest tube system?

Question

Quizplus · Accepted Answer

Adjust the vacuum regulator until gentle continuous bubbling is observed in the suction control chamber.Gentle continuous bubbling ensures that enough vacuum is being applied (greater than the water depth in the suction control chamber).However,the depth of water in the suction control chamber is what regulates the amount of subambient pressure applied to the patient's chest tube.Gentle,not vigorous,bubbling is important.Vigorous bubbling increases water evaporation in the suction control chamber,ultimately decreasing the level of subambient pressure applied to the patient's chest tube.
