Pulmonary function tests (also called PFTs or lung function tests) help determine how well your lungs are functioning. The results of these tests tell your health care provider how much air your lungs can hold, how quickly you can move air into and out of your lungs and how well your lungs are able to use oxygen and get rid of carbon dioxide. The tests help your health care provider determine if you have a lung disease, help provide a measure of how significant your lung disease is, and can show how well the treatment for your lung disease is working.
Pulmonary function testing is usually done by a specially trained respiratory therapist or technician. For most pulmonary function tests, you will be asked to wear a nose clip to make sure that no air passes through your nose during the test. You will be asked to breathe into a mouthpiece that is connected to a machine called a spirometer. The technician may encourage you to breathe deeply during parts of the test to get the best results. Following all of the technician's instructions will help provide the most accurate results.
Yes. You should take your medications as usual unless otherwise instructed.
If you need spirometry only, it should take only 30 minutes. If you need complete PFTs, it takes about one hour.
Pulmonary function testing helps the health care provider determine if you have a lung disease, helps provide a measure of how significant your lung disease is and can show how well the treatment for your lung disease is working. PFTs are interpreted by our pulmonologist, who is specially trained in pulmonary (lung) diseases and conditions.
The need for a pulmonary function test should be determined by your health care provider.
Your health care provider will decide how often you will need PFTs. This will depend on your medical condition, the medications you are taking and how well your disease is being managed.
The PFTs are interpreted by our pulmonologist, who is specially trained in pulmonary diseases and conditions. The test results and interpretation are sent to the health care provider who ordered the test for you.
