PFT

Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders.

Is PFT test painful?

The test does not hurt. You may feel symptoms of your lung condition during or immediately following testing.

Why PFT test is done?

This test is similar to spirometry. You breathe into a tube attached to a machine. The test can help diagnose a disease of the blood vessels between your heart and lungs, and it can show the amount of damage done by a disease such as emphysema, a disease in which your air sacs are gradually destroyed.
