Transfer Factor for the Lung and ‘Emphysema Score’

Abstract
The CO transfer factor for the lung was measured, Key Words using the breath-holding technique, in 37 patients with moderate or severe chronic obstructive lung disease, classified as ‘bronchitis Chronic bronchitis chilis’, ‘emphysema’, or ‘intermediate’ disease. A highly significant decrease of transfer factor and transfer coefficient was found in patients with emphysema as compared with bronchitis. The correlation between both gas-transfer parameters and ‘emphysema score’ was significant. The theoretical and clinical aspects of diffusing capacity determinations in patients with chronic obstructive lung disease are discussed
