medicine, applicable for examination of disturbances of blood filling and ventilation of lungs. SUBSTANCE: the method consists in measurement of breathing parameters of the patient at his placement in a weak homogeneous electromagnetic field at an intensity of 10 to 30 V/m. Measurements taken with the aid of a matrix of sensors installed opposite the rear surface of the chest. Prior to measurement of the breathing parameters, the coefficient of the patient's physiologic peculiarities is determined with due account made for the individual distinctions of his chest. After amplification and conversion the indications of the sensors in the digital form are processed in the computer, presented in the form of breathing curves in time, and the blood filling and ventilation of lungs and by each lung. For estimation of blood filling in them determined are the respective indices of blood filling uniformity. The flow- volume graphic dependencies for each lung are formed in the singled-out zone of the breathing curve (forced condition). EFFECT: enhanced truth of obtained data, their information fullness and enhanced accuracy. 5 cl, 8 dwg, 2 tbl
