An erythrocyte transport function (ETF) is proposed, as an index of the efficiency of the circulation of red cells. Under defined conditions, this ETF is shown to be proportional to the ratio of haematocrit to whole-blood viscosity (phi/eta), a ratio already used by Chien. The variations of phi/eta with phi, at selected driving pressures in a capillary viscometer, are presented, both for normal and for pathological blood samples. Maximal values of phi/eta appear generally to occur at… 
Plasma and serum viscosity in nigerian diabetics
TLDR
It is suggested that abnormally raised plasma and serum viscosities, by contributing to disturbances in normal blood flow and metabolism, may play an essential role in the development of both micro-circulatory disorders and hypertension in some Nigerian diabetics.
Improvements in blood rheology after cardiac rehabilitation and exercise training in patients with coronary heart disease.
TLDR
Cardiac rehabilitation improves blood rheology in patients with CHD by reducing mu45 and PV and elevating tau(rbc) and these improvements may contribute to the increased functional capacity and reduced morbidity and mortality that is associated with participation in cardiac rehabilitation and exercise programs.
Simple chronic transfusion therapy, a crucial therapeutic option for sickle cell disease, improves but does not normalize blood rheology: What should be our goals for transfusion therapy?

TLDR
Basic rheologic changes following transfusion inform other therapeutic options that aim to mitigate this diffuse pathologic process, and will aim to highlight transfusion effects on blood rheology.

Whole-blood viscosity, as determined by plasma viscosity, haematocrit, and shear.
TLDR
The present paper attempts to show how, in principle, a complete family of "constant-rate" (rotational) curves can be computer-plotted from two suitably-spaced capillary-tube measurements.
Paraproteinemia: blood hyperviscosity and clinical manifestations.
TLDR
Observations illustrate the complex relationship between blood viscosity, concentration of paraprotein, immunoglobulin class and hematocrit, and emphasize the importance of measuring the whole blood Viscosity at low rates of shear in determining the risk of vascular complications.
SERUM HYPERVISCOSITY SYNDROME.
TLDR
The hyperviscosity syndrome commonly includes mucous membrane bleeding, retinopathy and loss of vision, and neurological disorders associated with elevated serum viscosity, and is frequently seen in patients with macroglobulinemia, with or without demonstrable lymphoma, but only rarely with multiple myeloma.
