Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are functioning. The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and plan the line treatment of certain lung disorders. PFTs may be used to check lung function before surgery or other procedures in patients who have lung or heart problems, who are smokers, or who have other health conditions. Normal values for PFTs vary from person to person. The amount of air inhaled and exhaled in your test results are compared to the average for someone of the same age, height, sex, and race. Results are also compared to any of your previous test results. If you have abnormal PFT measurements or if your results have changed, you may need other tests.
