Abstract
Geography, or impedance plethysmography, is a method of studying the blood supply of organs and tissues by recording changes in their electrical resistance. A special case of this method is reopulmonography (RPG)-a method of assessing pulmonary circulation and ventilation. Electrical current resistance changes under conditions of pulsatile blood flow and breathing can be recorded graphically in the form of a characteristic periodic curve, the form of which depends on the functional and morphological state of the studied lung area. The configuration of the rheogram is close to the plethysmogram, but not identical to it, as it is determined not only by blood flow, but also by the blood flow rate in the studied area. This fact is clearly illustrated by RPE recordings from different parts of the lung.
