THE EFFECT OF GAS FLOWS OF VARIOUS DEGREES OF IONIZATION ON THE DIELECTRIC PARAMETERS OF BLOOD IN VITRO

Abstract

The aim of the study was to evaluate the dielectric properties of blood when treated with various ionized and non-ionized gas streams. Material and methods. The effects of gas flows were studied on 10 whole blood samples of practically healthy volunteers divided into 5 portions (control, treatment with helium, argon and cold plasma obtained from them for 1 min.). The dielectric properties of the biological fluid were studied by microwave dielectrometry on the permeability and conductivity of the biological fluid. Results. It was revealed that the presence of ionization and the type of carrier gas directly determine the nature of their effect on a model biological object (whole blood). It has been found that non-ionized helium and argon fluxes increase the permeability of the biological fluid without affecting its conductivity. On the contrary, ionized flows demonstrate more pronounced and specific shifts in the dielectric characteristics of blood. Helium cold plasma significantly increases the conductivity of the biological fluid while maintaining its conductivity, and argon plasma reduces both studied indicators.
