A Pulmonary function test (PFT) is a non-invasive test that shows how well the lungs are working. The test measure lung volumes, capacity, rates of flow, and gas exchange. This information can help your health care provider diagnose and decide the treatment of certain lung disorders.

There are many different reasons why PFT’s may be ordered: routine physicals, employee health exams, or just too simply help diagnose health problems.

Lightheaded / dizziness, shortness of breath, coughing. Your side effect may vary depending on your general health.

Because pulmonary function testing is not an invasive procedure, it is safe and quick for most people. But the person must be able to follow clear, simple directions.
