Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working. An FEV1 reading thats lower than expected shows you might have a significant breathing obstruction. Lung diffusion testing (ability of the body to absorb carbon monoxide from a single breath) is used to determine how well oxygen passes from the alveolar space (alveolar membrane permeability) of the lungs into the blood. Read the form carefully. Carbon monoxide is used to estimate gas transfer instead of oxygen due to its much higher affinity for hemoglobin. In very rare cases, pulmonary function testing may cause a collapsed lung (pneumothorax).

The appropriate treatment is usually corticosteroids to reduce the inflammation. The tests measure the amount of air you breathe out (exhale) and how long it takes for you to exhale completely.
