Because the test is so sensitive, it can detect problems earlier than other methods. This allows treatment and prevention measures to begin sooner, thereby improving patient outcome. It's more accurate than other techniques and is particularly useful for patients with advanced emphysema. It can also detect subtle changes in patients with airway diseases, such as asthma. Body plethysmographs are airtight, transparent chambers.
Patients sit inside and breathe into an air piece.
The test measures the amount of air in the lungs, how fast a patient can exhale air from the lungs, and how well oxygen travels from the lungs into the bloodstream. With this system, the test is done precisely and quickly, saving both time and health care dollars. If you are having breathing difficulties, please call your doctor for approval for this test.
