Abstract
Analysis of blood rheogram obtained by means of a Taylor-Couette rheometre (RV 100-CV 100) enabled us to define a new rheological index of blood deformability named δ, the unit ‘s-1’.
It corresponds to a shear rate for which the shear thinning effect provides blood with a quasi-Newtonian behaviour.
With 64 controls, this index and the other parameters of the rheogram have been calculated according to a structural rheological law.
This δ index is independent from the other parameters. Variations of the δ index can be observed among strokes and among pentoxyfillin-taker controls.
