Pulmonary Function Tests are available at the Northside Hospital Diagnostic Clinic for patients with asthma, emphysema and a variety of lung disorders.
While physical examinations tell your physician how your lungs sound and x-rays tell your physician how your lungs look, Pulmonary Function Tests tell your physician how your lungs perform.
Pulmonary Function Tests are easy to perform. For most PFTs, you will wear a nose clip to make sure no air passes in or out of your nose during the test. You will breathe into a mouthpiece attached to a recording device. You may be asked to breathe rapidly or normally, or to exhale and inhale deeply and forcibly.
The accuracy of the test depends on how well you follow all the instructions. The test may take from 5-30 minutes.
