Abstract

Dependence of the helium mixing time in the lung-spirograph system of factors influencing its value was analyzed. In the case of uniform ventilation of the lungs graphs were plotted by means of which the “ideal” mixing time was determined. It is suggested that nonuniformity of lung ventilation be judged by the amount by which the mixing time obtained during investigation of the patient's respiration exceeds the “ideal” time found for the same patient from the graph.
