Pulmonary Function Testing


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. Combined with your symptoms, PFTs are very important tests in making the diagnosis.

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.

Before your lung function testing your doctor and respiratory therapist will advise you to stop using certain medications.
