Water seal chest tube drainage system in upright position and below the level of the client’s chest. Tubing is free of kinks and patent. Suction is set at prescribed -20 mmHg.

Once placed, chest tubes may be attached to a PDU and set to active suction or to water seal, which is simple dependent drainage. The phrase “place a chest tube on water seal” is a misnomer, as modern PDUs have a constitutive water seal chamber that serves as a 1-way valve, preventing air from returning into the pleural space; placing a ...

Chest drains also known as under water sealed drains (UWSD) are a drainage system of three chambers consisting of a water seal, suction control and drainage collection chamber. UWSD are designed to allow air or fluid to be removed from the pleural cavity, while also preventing backflow of air or fluid into the pleural space.

The water in the water-seal chamber may rise with inhalation and fall with exhalation (this is called tidaling), which demonstrates that the chest tube is patent. Tidaling can also be seen in the drainage tube that connects the patient to the chest drainage unit.
