Hemorheological models applied to data analysis in groups of patients and in healthy subjects

An overview of some mathematical models describing the rheological behavior of blood is done. Several known models were used to describe the non-Newtonian rheological properties of blood. The parameters of two of the simplest models - the power law and the Herschel-Bulkley law were used to analyze the differences between the microrheological and micromechanical characteristics of blood in a group of patients with diabetes mellitus type 2 (T2DM) and in healthy subjects. The experiments were carried out with Low Shear 30 (LS 30) Contraves viscometer in a wide range of shear rates. All experimental data were statistically processed using the Mann-Whitney U-test for intergroup comparison of independent variables, as well as the t-test. The Statistica program was used for statistical processing. The results obtained are compared with the hemorheological models from other disease states.
