WebThese three measurements are crucial for figuring out how well the lungs are working. The amount of air a person can forcibly exhale in one second is measured by their forced expiratory volume in one second (FEV1%). This test is significant in determining how well the lungs are working generally since it indicates the level of airway blockage. WebA low FEV1 may suggest an obstructive lung disease (e.g., asthma or COPD). ... and pulmonary rehabilitation to improve airflow and reduce symptoms. For restrictive lung diseases, treatment options may consist of medications to reduce inflammation, supplemental oxygen therapy, and pulmonary rehabilitation to enhance lung function and …

The ratio of FEV1 to FVC compares the amount of air that can be forcefully expelled in one second to the amount that can be expelled in total. A normal FEV1/FVC ratio is 70% to 80% or higher in adults and 85% or higher in children. 2. WebIn individuals without obstruction or restriction at baseline, the rates of FEV1 decline of 60 to <90 ml/y and of ≥90 ml/y were associated with 1.6 (95%CI 1.1-2.6) and 2.2 (95% CI 1.3-3.5) times higher risk of death in comparison to those with the rate of decline <30 ml/y (5).
