Plethysmography and roentgenography were performed on normal subjects and patients with emphysema. 23 measurements from postero-anterior and lateral roentgenograms were subjected to discriminant and regression analyses to discover (a) which variable(s) best distinguished normal from overinflated lungs and (b) whether these or other variables could be used to predict total lung capacity. A combination of measurements was found to work best in each case.
