Your FEV1 value is an important part of evaluating chronic obstructive pulmonary disease (COPD) and monitoring progression of the condition. For well over thirty years my lab has used an FEV1/FVC ratio of 95% of predicted as the cutoff for normalcy. FVC is the … Forced vital capacity (FVC) is the total amount of air exhaled during the FEV test. FEV1 and FVC are tests used in the diagnosis of various lung diseases.

Among smokers, FEV1% detected abnormality in 19% while FEF 25-75% only in 7% and among the allergic subjects the former detected abnormality in 25% while the latter only in 19%.

FEV1 is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms The Free Dictionary FVC stands for forced vital capacity— the amount of air that you completely exhale in one breath.
