Abstract
The results of the study of the possibility of applying the results of the bioimpedancometry method for hidden and spontaneous bleeding monitoring are presented. The current problem of blood loss metering for during resuscitation, surgery and rehabilitation activities is shown. The use, as informative parameters, of the spectral properties of the bioimpedance signal, namely, the coefficient of inter-spectral correlation of the original measurement signal and its linear transformation, is proposed. In work, the existing biophysical models that substantiate the prospects of using the bioimpedance method for similar problems are considered in detail. Calculated empirical expressions for determining the volume of liquid segments of the human body are presented. The mathematical substantiation of the method of inter-spectral correlation based on the calculation of the correlation coefficients of the wavelet-decomposition coefficients of the original signal and its linear transformation is given. The results of experimental studies on the approbation of this method for fixed venous blood sampling are presented in the work. Using criterial T-statistics, a quantitative evaluation of the effectiveness of the options for choosing the spatial placement of measuring electrodes in bioimpedancometry was carried out. The obtained results allow us to conclude that the proposed method is feasible and promising for real-time monitoring of the onset of latent and spontaneous bleeding. Also, the obtained results make it possible to formulate recommendations for the placement of measuring electrodes on the patient's body.
