[The assessment of microcirculation based on mathematical models of the hydrodynamics and oxygen transport in the microvessels (II)].
Our previous communication No. 1 presents a mathematical definition of dynamic hematocrit and rate of erythrocyte movement, based on microvessel hemodynamics model. Now we offer a mathematical model of convective diffusion oxygen transfer in the erythrocytic cylinder-plasma system. Another definition of erythrocyte movement rate is offered and a solution of two equations which permitted its definition by measured parameters. A series of practical formulae for estimating microhemodynamics is derived, which can be used in clinical practice. The proposed model has been used in cardiosurgery department of Research Center of Surgery.
