WebJan 17, 2024 · The two most often used measurements are FVC (forced vital capacity) and FEV1 (forced expiratory volume in one second). An FEV1/FVC ratio of >80% indicates a restrictive lung disease like pulmonary fibrosis or infant respiratory distress syndrome. An FEV1/FVC ratio of <70% indicates an obstructive lung disease like asthma or COPD. WebFEV1 and FVC are related and followed closely. FEV1 and FVC Ratio FVC can decrease in a similar way in both obstructive lung diseases (COPD) and restrictive lung diseases (pulmonary fibrosis).

FEV stands for forced expiratory … 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.
