WebAug 17, 2024 · Spirometry (spy-ROM-uh-tree) is a common office test used to assess how well your lungs work by measuring how much air you inhale, how much you exhale and how quickly you exhale. Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing. WebJun 28, 2024 · The FEV1/FVC ratio can also be used to figure out the severity of obstructive lung disease. Total lung capacity (TLC): Total lung capacity (TLC) is calculated by adding the volume of air left in the lungs after exhalation (the residual volume) to the FVC. TLC is normal or increased in obstructive defects and decreased in restrictive ones.
