Pulmonary function testing (PFT), refers to a group of tests that measure how well your lungs are performing. One of these is called a spirometry test, which measures the ability to inhale and exhale. Pulmonary tests are often performed to diagnose certain types of lung disease such as bronchitis, asthma, emphysema, or chronic obstructive pulmonary disease (COPD). However, there are other reasons that someone may suggest a PFT. You’ll find PFT testing capabilities at a FastMed near you. If your physician has told you to get a PFT, and you’re not sure what to expect, we’re happy to help.

A PFT helps providers diagnose specific lung diseases by testing respiratory (lung) volumes and capacities. After spirometry testing, a total lung capacity chart will show whether the patient’s lungs perform at normal values or not. Besides diagnosing diseases, a PFT may be suggested to find the cause of shortness of breath, measure whether exposure to certain chemicals affect lung function (especially in people who are exposed to chemicals as part of their job), or to monitor lung capacity and function before surgery.
