A pulmonary function test or PFT helps a provider to evaluate respiratory function of the lungs and chest wall. This test is commonly used to evaluate shortness of breath and to help detect and classify pulmonary disorders by evaluating lung volume and capacity. PFTs can be used to monitor conditions such as asthma, allergies, and chronic obstructive pulmonary disease (COPD). A spirometer is an instrument used to measure the air taken in and expelled by the lungs. A successful spirometry test depends on proper patient preparation and consistent technique while the test is being administered.
