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.
Why would a pulmonary function test be ordered?

How do I read my PFT results?
This number represents the percent of the lung size (FVC) that can be exhaled in one second. For example, if the FEV1 is 4 and the FVC is 5, then the FEV1/ FVC ratio would be 4/5 or 80%. This means the individual can breath out 80% of the inhaled air in the lungs in one second.
How long does it take to get results of a pulmonary function test?

The normal ranges for pulmonary function tests vary by test type, according to the American Academy of Family Physicians. Some normal ranges are values between 80 and 120 percent for the FEV1 test, and values between 80 and 120 percent for the FVC.
What are the results of a pulmonary function test?
Other pulmonary function test results can show how fast gas is exchanged from the lungs into the blood. If there is a problem it will go on to affect all areas of the body. This other pulmonary function test is known as a gas diffusion test. It is mainly used to show how much carbon dioxide is exchanged by the alveoli.
What is a normal pulmonary function test?
Pulmonary Function Test. A pulmonary function test (PFT) evaluates how well the lungs are working. The test measures how much air the lungs can hold, and how well the child can push air out of his or her lungs.
