In patients with COPD, the amount of air left in the lungs during the breathing process is more than normal. Body plethysmography helps your doctor know more about your lung disease and how to treat it.
How the Test is Performed
You will be required to sit in an enclosed plastic box and then, wearing a nosepiece, you will be instructed on how to breath through a mouthpiece.
There are no significant risks involved with this test, however, if you have problems with claustrophobia, you may want to talk with your doctor about this prior to the test.
