Pulmonary Function Tests
Lung function tests, also called pulmonary function tests or PFTs, evaluate how well your lungs work.
The tests determine how much air your lungs can hold, how quickly you can move air in and out of your lungs, and how well your lungs put oxygen into and remove carbon dioxide from your blood.
The tests can diagnose lung diseases, measure the severity of lung problems, and check to see how well treatment for a lung disease is working.
For this test, you breathe into a mouthpiece attached to a recording device called a spirometer. The information collected by the spirometer is printed out on a chart called a spirogram, which is sent to your company for recordkeeping and compliance.
