Abstract:

Objective — to compare the temporal dynamics of the tissue impedance of human and pig corpses under the same conditions to substantiate the further use of pig corpses as model objects. At the first stage, we studied the tissue impedance values obtained on 4 pig cadavers with a known date of death measured with a Keysight U1731 parting. The necessity of using a model object for studying the dynamics of impedance in the postmortem period has been substantiated. An exploratory analysis was carried out that allows to put forward a hypothesis about the existence of the impedance values (absolute indicators) and dispersion coefficients (relative indicators) dependence on the time of death, and also suggests that the combination of impedance values and the corresponding coefficients can be used to judge its duration for the objects under study.
