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 …

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).
