Forced expiratory volume (FEV) measures how much air a person can exhale during a forced breath. It records how much air you blow out (FVC, or forced vital capacity) and how quickly you do it (FEV, or forced expiratory volume). It is Forced Expiratory Volume In One Second/Forced Vital Capacity. A higher slow vital capacity (VC) compared with forced vital capacity (FVC) indicates small airway collapse and air trapping. Forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) variability in asymptomatic never-smoking men. Forced expiratory volume is the most important measurement of lung function.

The amount of air exhaled may be measured during the first (FEV1), second (FEV2), and/or third seconds (FEV3) of the forced breath. While FVC cannot identify which specific lung disease you have, the results can help narrow down potential diagnoses and can be used—along with other studies—to help in determining which lung disease you have. The 2005 American Thoracic Society (ATS)/European Respiratory Society (ERS) spirometry guidelines define valid tests as having three acceptable blows and a repeatable forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1). The authors analyzed 44,664 annual measurements of forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) in 12,258 white children and 1,041 black children between 6 and 11 years of age in 6 communities.
