The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders. There are 2 types of disorders that cause problems with air
Forced expiratory flow (FEF). This is the average rate of flow during the FVC test. The usual discrete intervals are at 25%, 50%, and 75% of the FVC exhaled (FEF25, FEF50, and FEF75). It can also be given as a mean of the flow during an interval, usually 25–75% (FEF25–75%). Peak expiratory flow rate (PEFR).Pulmonary Function Tests for Lung Disease,2020-3-24 · What to Expect. Pulmonary function tests (PFTs) are used to assess various aspects of your lung function. These noninvasive tests—spirometry, the lung diffusion test, and lung plethysmography—are used to help diagnose lung diseases like COPD, as well as to determine how treatment is working and if such a condition is progressing.
