The kinetics of conductivity signals were recorded both under transient flow and after the complete stoppage of shearing at shear rates from 0.94 to 94.5 s-1 and temperatures T = 25 oC and 37 oC. The obtained experimental relationships show that the human blood conductivity is time, shear rate, hematocrit and temperature dependent under transient flow. The results also show that valuable information could be received about the kinetics of rouleaux formation and suggest that the technique may be used to clarify the mechanism of dynamics of RBC aggregates.
