WebFEV1 and FVC Ratio. FVC can decrease in a similar way in both obstructive lung diseases (COPD) and restrictive lung diseases (pulmonary fibrosis). Often, 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. balai polis bandar 32
