What is Body Plethysmography?
Body plethysmography is a test which measures the volume of the lungs and the sum of various segmental volumes of the thorax. This is a test that is usually complementary of spirometry.
It requires special equipment, the “body box”. Thus, during boy plethysmography, the examinee sits within an airtightly sealed chamber and inhales and exhales in a special tube which is connected to a computer. Plethysmography is painless, without any complications for the patient and is often necessary both for the diagnosis of various respiratory diseases and for their monitoring over time.
