a
Blood shear rate = 200/sec
b
blood shear rate = 3/sec. Points assigned as a measure of the blood viscosity of patients, and were a comprehensive indicator, which included the plasma viscosity, haematocrit, erythrocyte deformation, erythrocyte aggregation, platelet rheology and leukocyte rheology. Higher scores indicated a higher blood viscosity. BVH, blood viscosity of high cut; BVL, blood viscosity of low cut; PV, plasma viscosity; RBCAI, red blood cell aggregation index; BRV, whole blood reduced viscosity; RBCET, red blood cell electrophoresis time.
