Does Emphysema Decrease FVC?
Does Emphysema Decrease FVC? Does emphysema decrease FVC? A reduction in elastic recoil forces of the lung in emphysema results in several unwanted outcomes. First, airway collapse on forced expiration is accentuated, resulting in a reduced FEV1 and reduced FEV1/FVC ratio, and thus an obstructive ventilatory defect on spirometry. What causes a decrease in FVC?
