[A physical model of gravitational erythrocyte sedimentation].
A model of erythrocyte sedimentation under gravity is proposed. The model is based on two-phase description of the blood and it involves a kinetic equation of erythrocyte aggregation. A method of characteristics is employed for analysing the physical pattern of sedimentation for different hematocrit. An approximate decision for trajectory of the interface between pure plasma and low-located region of the erythrocyte suspension is obtained. By utilizing this decision the simple coefficient of the erythrocyte aggregation ability calculated in terms of hematocrit and erythrocyte sedimentation rate is possible.
