Pulmonary function testing (PFT) is a method of determining how well a patients lungs and airways are working. PFTs may be done on a routine basis and enables our physicians to compare each patient's lung function with a predicted value based on age, height, and sex, as well as their lung function in the past. Closely following these tests allows our physicians to intervene early when lung function is failing and to fine-tune patient therapy.

The term Pulmonary Function Test is a general term; there are many pulmonary function tests. Each test performed will yield different information. The most common pulmonary function test is called spirometry. During this test the patient inhales as deeply as possible, and then exhales with as much force as possible. Several attempts at this procedure to ensure that the paitent is being evaluated at his or her optimal performance level. Patients will be tested before and after breathing in a bronchodilator. Changes that may occur after allows our physicians to make appropriate changes in your therapy.

The second common pulmonary function test is called lung volumes. This test is usually done in a body plethysmograph or "body box." A body box is a clear plexi-glass booth, in which the patients are situated for testing. Measurements taken by the body bos can calculate the total amount of air in a patients lungs upon complete exhalation. The total amount of air in a patients lungs after a full inspiration is called total lung capacity. The amount of air in the lungs after the patient has fully exhaled is called residual volume. The ratio of these two numbers is a sensitive measure of lung disease.

Our clinic has a state-of-the-art pulmonary function laboratory as well as a chest x-ray department. Our pulmonary function lab and chest x-ray department enable us to deliver high quality pulmonary tests and x-rays to assist in the diagnosis and monitoring of respiratory diseases. We are also able to provide a variety of diagnostic studies to help physicians better assess their patients who might have respiratory symptoms and/or limitations. The pulmonary lab can also provide the diagnostic tools to augment other procedures in order for the physician to reach a definitive diagnosis. In order to achieve a high standard of service and patient care, we are able provide our pulmonary services and chest x-ray results with interpretation to physicians and patients within a 24-hour turn-around time.

Our list of laboratory and radiology services includes:

  • Spirometry, pre and post bronchodilator
  • Lung volumes (via body pethsmography or helium dilution)
  • Diffusion Lung Carbon Monoxide
  • Arterial Blood gases
  • Methacholine Bronchoprovocation Challenge
  • Cardiac Stress test
  • One, two and four view Chest X-rays
