[Dynamics of oxygen transport in erythrocytes]

Distribution dynamics of oxygen tension throughout the erythrocyte volume was calculated by means of a mathematical model describing the dynamics of oxygen transport in the erythrocyte, its shape, diffusion resistance of hemoglobin solution. The pattern of the dissociation curve of oxyhemoglobin being taken into account. The model is presented as a system of differential equations in partial derivatives. Its solution was performed on an electron computer by a net method. Sharp jumps of pO2 inside the erythrocyte at its fast movements in the media with different partial pressure of O2 were shown. A quantitative relationship was found between the rate of physico-chemical reactions of oxygen binding and yield by hemoglobin and the level of hemoglobin saturation with oxygen.
