Forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) were measured at baseline and 3-year follow-up using standard spirometry . Objective. To compare the rate of respiratory decline using percent normal forced vital capacity (%FVC) measurements before and after posterior sp...
The FVC is the forced vital capacity. It requires that the subject make a maximal inspiration to TLC, then make a maximal forced expiratory effort, leaving only the RV. In a normal subject, the FEV1/FVC is greater than 0.8; patients with obstructive lung disease, such as asthma or COPD,...

There was no significant difference between FVC, SVC, and IVC in normal subjects. However, the three measurements of vital capacity were significantly different in all subgroups of asthmatics. FVC was smaller than both SVC and IVC. The differences were more marked in patients with moderate and ...
Introduction: A restrictive ventilatory defect (RVD) is confirmed on the basis of a decrease in total lung capacity (TLC). According to the ATS/ERS 2021, the presence of restrictive impairment in an obstructed patient cannot be deduced from forced vital capacity (FVC) simple measurement. Aim. ...
