Thoracentesis

Overview

Thoracentesis is a procedure used to take out fluid that has built up between the lungs and chest wall. This can help reduce pressure and improve breathing.

• Also called a pleural tap
• Often used when fluid causes shortness of breath
• Fluid can be tested to find out why it’s there

Candidates for thoracentesis

Thoracentesis may be recommended if you have signs of fluid buildup in your chest.

• People with lung infections like pneumonia or TB
• People with heart or liver failure
• People with cancer that has spread to the lungs
• People with breathing trouble from fluid in the chest
