Discharge Instructions for Thoracentesis
Thoracentesis is a procedure that removes excess fluid from the pleural space. This space is between the outside surface of the lungs (pleura) and the chest wall. The procedure may be done to take a sample of the fluid for testing. Or, if you are having symptoms such as trouble breathing, it may be done to drain the excess fluid.

Thoracentesis removes excess fluid from the space around the lungs.
