WebIn summary, reversibility of airflow obstruction in asthma is defined by an increase in FEV1 of 12% or 200 ml. There is generally an increase in FEV1/FVC since FVC changes less than FEV1, making FVC a less useful parameter for assessing reversibility. Some patients, particularly with severe COPD, may show a greater response of FVC than FEV1. Web1/FVC declines as asthma severity increases.
