摘要：
FIELD: medicine.SUBSTANCE: invention relates to medicine, can be used to assess the functional state of the organism. As components of the impedance of the biological object, the active resistance R and the equivalent capacitance C of the bio-object tissues are determined. In this case a stabilized current pulse I0 is applied to the bioobject and the voltage Ui at time ti after the start of the current pulse. Maximum value of the potential E is determined from the calibration characteristic. Calibration is carried out a priori for two voltage values: the measured Ui and known reference Uei, where i=1, 2, at two instants of time t1 and t2=2t1. Calibration characteristic is the function of the maximum value of the potential E0i compensating for the uncertainty of the T time constant by arbitrarily chosen T* and connecting the reference Uei and the measured Ui characteristics of the definition of impedance due to the normalization of the measured values by known ones. Further on the values of the lower E01 and upper E02 range limits of the calibration characteristic E0i find the real values of the T time constant and the maximum value of the potential E , the calibration characteristic E0i and the real U∂i characteristic of the definition of impedance are gradually constructed on their bases, said characteristic is maximally close to the reference Uei=U∂i. Taking into account the calculated values of E and T, the components of the impedance R and C of the biological object are determined.EFFECT: method provides an improvement in the accuracy of determining the actual impedance characteristic due to the calibration characteristic compensating for the uncertainty of the time constant selected arbitrarily.1 cl, 4 dwgИзобретение относится к медицине, может быть использовано для оценки функционального состояния организма.
