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 If the FVC and the FEV1 are within 80% of the reference value, the results are considered normal. 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.

Leone N Using the lower limit of normal for the FEV1 /FVC ratio reduces the misclassification of airway obstruction.

The FEV1/FVC ratio, also called Tiffeneau-Pinelli index, is a calculated ratio used in the diagnosis of obstructive and restrictive lung disease. It represents the proportion of a person's vital capacity that they are able to expire in the first second of forced expiration to the full, forced vital capacity ().

2012-07-04 · Background Recent studies have showed that FEV1/FVC describing correspondence between the forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) depends significantly on age. However, the nature of this dependence is uncertain. The study aim is to analyze mathematically the relationship between FEV1 and FVC to find a cause of the FEV1/FVC dependence on age in healthy

It's used as a common indexes in the diagnosis of airway obstructive and restrictive lung disease. It is the measure of maximum amount of air that an person can exhale forcefully in a second. FEV1 is the standard unit of measurement used by doctors to analyze the respiratory health. fvc 92 fev1 88 fev1/fvc 84 one year later fvc 93 fev1 83 fev1/fvc 87.should i be concerned that the fev1 has declined? no change post bronch.
