Pulmonary Function Tests (PFTs)

Pulmonologists from the Division of Pulmonary and Critical Care Medicine and certified pulmonary function technicians will perform your pulmonary function tests.

What Do Pulmonary Function Tests Involve?

PFTs are noninvasive diagnostic tests that provide measurable feedback about the function of the lungs. By assessing lung volumes, capacities, rates of flow and gas exchange, PFTs provide information that, when evaluated by your physician, can help diagnosis certain lung disorders. This test will also determine your eligibility for heart transplantation.

Spirometry for Evaluating Lung Function

Spirometry is a type of pulmonary function test that is used in the evaluation of lung function. During a spirometry, our technicians will ask you to exhale air into a measuring device known as a spirometer, which measures your exhaled volume and airflow. If you've already been diagnosed with a chronic lung disorder, spirometry can be used to check how well your lungs are functioning.

Once a diagnosis is made, you will be referred to Jefferson physicians who will deliver comprehensive therapeutic services for the entire spectrum of diseases that affect the respiratory system. Our staff also collaborates with Jefferson thoracic surgeons, should surgical intervention be required.
