Body plethysmography is a pulmonary function test that determines how much air is in your lungs after you take in a deep breath. It also measures the amount of air left in your lungs after you exhale as much as you can. During this test, a person sits or stands inside an air-tight box that resembles a short, square telephone booth to perform the tests. Changes in pressure inside the box help determine the lung volume during various respiratory maneuvers. Each of our locations is equipped with a body plethysmograph. In addition to providing complete lung volume measurements, this test is especially useful for the evaluation of patients with restrictive lung diseases such as interstitial lung diseases, sickle cell disease, chronic lung disease related to neuromuscular disorders, pneumonia and chest wall abnormalities including pectus excavatum and severe scoliosis. It can help determine the ability of a patient to tolerate surgery, medical procedures or aggressive treatment such as chemotherapy.
