The most common parameters measured in spirometry are Vital capacity (VC), Forced vital capacity (FVC), Forced expiratory volume (FEV) at timed intervals of 0.5, 1.0 (FEV1), 2.0, and 3.0 seconds, forced expiratory flow 25–75% (FEF 25–75) and maximal voluntary ventilation (MVV), also known as Maximum breathing capacity.

The FEV1/FVC ratio is the ratio of the forced expiratory volume in the first one second to the forced vital capacity of the lungs. The normal value for this ratio is  Predicted Range. Spirometry in Obstructive Defect. FVC. FEV1.

There was a significant positive correlation between VO2max percent predicted and FEV1 percent predicted (p < 0.02), and a negative correlation between FEV1 and end-expiratory lung volume (EELV) at maximal FEV1/FVC ratio as low as 50 % The FEV1/FEV6 ratio below LLN has a positive and negative predictive value of 97 % for diagnosis of airway obstruction When using fixed cut-offs, one may refers to the conclusion by two large population studies that FEV1/FEV6 < 0.73 is an valid alternative to the FEV1/FVC < 0.70 to diagnose airflow obstruction FEV1 may be a better indicator than vital capacity – if FEV1 is > 2L, mortality is ~ 10%, whereas for FEV1 < 1L, mortality may increase to > 20% [Lockwood P. Respiration 30: 529, 1973].

The most common parameters measured in spirometry are Vital capacity (VC), Forced vital capacity (FVC), Forced expiratory volume (FEV) at timed intervals of 0.5, 1.0 (FEV1), 2.0, and 3.0 seconds, forced expiratory flow 25–75% (FEF 25–75) and maximal voluntary ventilation (MVV), also known as Maximum breathing capacity.

FEV1/FVC ratio. Doctors often analyze the FVC and FEV1 separately, and then calculate your FEV1/FVC ratio. The FEV1/FVC ratio is a number that represents the percentage of your lung capacity you

A fixed ratio FEV1/VC <0.7 (FR) or a use of the age-related lower limit of normal for FEV1/VC (LLN) are the most common definitions. We analysed respiratory symptoms and extensive lung function in groups of subjects fulfilling none, either or both of the spirometric criteria Visible test group measured value of 1.06 ± 0.30, Efremidis et al projected VO2max 2.59 ± 0.71, t = 20.267, P lt; 0.001 3 to age, height, weight, BMI, BAS, FVC, FEV1, FEF3 FEF25-75%, FEF50%, FEF75%, PEF, MVV, VC, IC, TLC, RV, DLCO, Raw as independent variables, maximal oxygen uptake as the dependent variable, multiple linear regression, stepwise regression analysis formula to predict the FEV1 is a measurement used to stage and diagnose lung diseases.

The normal value for the FEV1/FVC ratio is 70% (and 65% in persons older than age 65). When compared to the reference value, a lower measured value corresponds to a more severe lung abnormality.

The small decrease of FEVI/VC% in our symptomatic subjects had no effect on bronchial hyperreactivity. Interestingly, our subjects showed a FEV1/VC is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms. FEV1/VC - What does FEV1/VC stand for?

Definition of FEV1 /FVC in the Medical Dictionary by The Free Dictionary

FEV1/FVC showed 100% agreement with forced expiratory flow (FEF)=25-75%, and Maximum expiratory flow (MEF)=50% but this agreement for FEV1/VC was 95-96%. Rapti Mediwake MD, Roland M. du Bois Elliott, in Systemic Lupus Erythematosus, 2007.
