It represents the proportion of a person's vital capacity that they are able to expire in the first second of forced expiration (FEV1) to the full, forced vital capacity (FVC). The result of this ratio is expressed as FEV1%. orbitloot.com

WebConclusions: A reduced FEV 1 /FVC may be a normal finding in younger-to-middle age male subjects with an FVC% value above the mean predicted value, especially when terminal flow is within the normal range. Keywords: airway obstruction; asthma; chronic obstructive pulmonary disease; expiratory flow; lung function; lung functions testing; spirometry. 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 …
