The formula for the predicted FEV1 is published by the Association for Respiratory Technology and Physiology ( It is based on a regression model from a cohort of subjects aged 18-60, and included height, age and gender. The predicted FEV1 is calculated using the formula FEV1{litres} = 4.30*height{metres} - 0.029*age{years} - 2.49. The formula for the predicted FEV1 is published by the Association for Respiratory Technology and Physiology (

FEV 1 or FVC do not decrease unless patients are massively obese. The FEV 1 /FVC ratio is also preserved. 1, 16, 18–20, 24, 25, 27, 30, 33, 34 One large study found that BMI had a modest, inverse correlation with FEV 1 and FVC in men but only a trend in women. FEV 1 in men with a mean BMI of 33.6 kg/m 2 was nearly For example, if the FEV1 is 4 and the FVC is 5, then the FEV1/ FVC ratio would be 4/5 or 80%. This means the individual can breath out 80% of the inhaled air in the lungs in one second. FEV1/FVC Ratio Interpretation – The three key spirometry measurements (the FVC, FEV1 and FEV1/FVC ratio) for a given individual are compared to reference values.

FEV1 is the standard unit of measurement used by doctors to analyze the respiratory health. FEV1 – The second is the forced expiratory volume-one second (FEV1). This is a measure of how much air can be exhaled in one second following a deep inhalation. Apart from these, there is another important aspect of the spirometry result the FEV1/ FVC ratio. This number represents the percent of the lung size (FVC) that can be exhaled in one 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 If the FVC and the FEV1 are within 80% of the reference value, the results are considered normal.
