A pulmonary function test (PFT) is designed to determine how well your lungs function and include measuring your lung volume and capacity as well as how effective your lungs are at delivering oxygen throughout your body.

A pulmonary function test may be performed if you are showing symptoms of a lung condition or before or following surgery. These tests are also recommended for patients with chronic lung diseases to monitor treatment progress and patient condition.

Pulmonary function tests are non-invasive and used to help doctors diagnose and decide the best course of treatment for certain lung disorders.

Generally, we recommend patients stop taking certain medications that could complicate the test and to avoid eating a heavy meal before their appointment. If you smoke, make sure to ask how many hours before the test you should avoid smoking.

Throughout the test, you will be asked to inhale and exhale in different ways and a nose clip may be used to prevent you from breathing through your nose. Once complete, your doctor will discuss your test results with you and the best treatment options as necessary.
