Fev-1 % predicted

WebOften, doctors use the FVC and FEV1 ratios to figure out the specific type of lung disease. For example, when FEV1 values make up less than 80% of the FVC, an obstructive lung disease is likely present. However, in restrictive lung diseases, both the FEV1 and FVC measurements decrease proportionally. WebFEV 1 > 60% but < 80% of predicted FEV 1 /FVC normal: FEV 1 < 60% of predicted FEV 1 /FVC reduced > 5%: Risk: Exacerbations requiring oral systemic corticosteroids: 0 to 1 per year ...
