| Abstract: | Segmentary topography of the air volume was studied by regional electroplethysmography of the lungs. A distinct apical-basal gradient was shown to be present in men tested in supine position, along with the dorsal-ventral gradient; the origin of the apical-basal gradient could not be explained from the point of view of the gravitational mechanism. A possibility of recalculation of the electroplethysmographic index of the percentage of the air content in the lobe of the lung to the regional air volume index in the lungs, and the principal possibility of calculation of the regional total lung capacity index with the help of electroplethysmography was shown. |
