WebA reduced FVC may indicate a restrictive lung disease (e.g., pulmonary fibrosis) or a neuromuscular disorder. Forced Expiratory Volume in 1 second (FEV1): The volume of air you can forcefully exhale in the first second of the FVC maneuver. A low FEV1 may suggest an obstructive lung disease (e.g., asthma or COPD). WebBackground: FVC may underestimate the slow vital capacity (SVC) due to early closure of the small airways at low lung volumes in the forced maneuver. It remains unclear whether using SVC instead of FVC in the FEV 1 /vital capacity (VC) ratio increases the yield of spirometry in detecting airflow limitation or, alternatively, leads to a false-positive finding … how to stop excel from deleting 0s
