[Lung study in bronchial asthma using x-ray pneumopolygraphy]

Roentgenpneumopolygraphy (RPPG) was used to examine 48 patients with bronchial asthma and all patients showed a reduction of one or several indices of zonal ventilation and/or biomechanics of the respiratory act. Inhalation of broncholytics improved all indices of RPPG. But most patients revealed local disorders of ventilation resistant to the effect of broncholytic agents. Local therapy of the corresponding lung regions produced a positive effect.
