Abstract

The effect of artificial pneumothorax on vital capacity has been studied by various observers, including Bendove,1 Anthony and Heine,2 Schill,3 Sieper4 and Kochs,5 by the usual methods of spirometry. However, reports of complete studies of the volume of the lungs are extremely rare, since the determination of the residual air (or the subtidal volume) depends on indirect measurements by some gas dilution and rebreathing technic. We are familiar with only one study on artificial pneumothorax in which such complete data are given (Anthony and Heine6). This work deals with the effects of artificial pneumothorax in collapse therapy for pulmonary tuberculosis. In their study, readings of intrapleural pressure are not recorded, nor are roentgen studies complete. Determination of residual air was made by a hydrogen dilution method.

The employment of artificial pneumothorax in the treatment of lobar pneumonia in children at this hospital in an
