The primary test done in our office is called a Pulmonary Function test or PFT. Pulmonary function tests are a group of tests that measure how well the lungs take in and release air and how well they move gases such as oxygen from the atmosphere into the body’s circulation. In this test, you breathe into a mouthpiece that is connected to an instrument called a spirometer. The spirometer records the amount and the rate of air that you breathe in and out over a period of time. Since the test involves some forced breathing and rapid breathing, you may have some temporary shortness of breath or lightheadedness. You breathe through a tight-fitting mouthpiece, and you’ll have nose clips. Any special instructions will be given prior to your appointment.
Pulmonary function tests are done to diagnose certain types of lung disease such as asthma, bronchitis, and emphysema. They can also be done to assess the effect of certain medications such as albuterol and measure the progress of treatment. Spirometry measures airflow. By measuring how much air you exhale, and how quickly, spirometry can evaluate a broad range of lung diseases.
