WebForced Vital Capacity. 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 FEV 1 /FVC is greater than 0.8; patients with obstructive lung disease, such as asthma or COPD, show a decreased FEV 1 /FVC. WebAug 17, 2024 · Forced vital capacity (FVC). This is the largest amount of air that you can forcefully exhale after breathing in as deeply as you can. A lower than normal FVC reading indicates restricted breathing. Forced … WebLook at the FEV1 (FEV1/FVC) and FVC individually. Their value in liters can be reduced below 80% either by restriction or obstruction. If the TLC is low, this is likely due to restriction. If the TLC is normal or increased the FEV1 and FVC may be reduced due to obstruction (see steps 3 and 5 to confirm). ca public health form 530
