Simulation of the O2 dynamic transport in the erythrocytes and blood plasma in capillary

A model of diffusive О2 transport in erythrocyte and surrounding plasma is suggested which allows for the calculation of pО2 distribution in a 3-dimensional capillary region. The dynamics of О2 diffusion inside and outside erythrocyte and reaction kinetics of red blood cells are considered. The finite differential method is used to obtain pО2 profiles as a solution of the differential equations. The resulting pО2 profiles exhibit large peri-oxygemoglobin and small plasma pО2 gradients. Such O2 transport peculiarity in capillary creates optimal conditions for О2 supply of tissues.
