What happens during the procedure?

The precise nature of the lung volume study will vary depending on which test is performed. In one test, known as body plethysmography, the patient sits inside a booth and breathes in and out of a mouthpiece. The air pressure inside the booth is measured. Other tests use a separate chamber attached to the mouthpiece to determine lung volume.
