Abstract
Measurements of vital capacity and maximal breathing capacity can be made with the help of a gas meter, graduated in liters, in place of the usual laboratory spirometer. The accuracy of the gas meter, as compared with the spirometer, was tested with both normal and abnormal subjects, and was found sufficient to give useful diagnostic information and to help in judging the progress of patients with disease of the heart or lungs.
