The fact that whole blood behaves as a non-Newtonian fluid has been known for many years. But the fact that numerous papers continue to appear in the literature which attempt to explain the so-called “anomalous” viscous behavior of blood is an indication that the meaning of non-Newtonian viscosity is not generally understood, and its significance ...

Blood viscosity and blood pressure
Pathology, 1981The viscosity of blood from 214 men and 206 women visiting a health screening clinic was measured with a recently developed Sydney Hospital viscometer at shear rates 0.1, 1.0 and 100 sec-1. A significant positive correlation (P P >0.01, r = 0.15) at 0.1 sec-1. It is suggested that this sex-specificity may be related to that found by investigators who

Whole blood viscosity in preeclampsia
American Journal of Obstetrics and Gynecology, 1982Whole blood viscosity was measured in 41 patients with preeclampsia and in 51 normotensive control subjects. The mean viscosity in the preeclamptic group had a highly significant elevation (t = 9.752, p less than 0.001, at a shear rate of 0.1 sec-1 and t = 4.223, p less than 0.001, at a shear rate of 100 sec-1).

Portal Hypertension and Blood Viscosity
Journal of Clinical Gastroenterology, 2007Previous studies, exploring the effect of blood viscosity on portal pressure in portal hypertensive humans and animal models, have shown conflicting results. In a series of studies, in portal vein constricted rats, we investigated effects of reduced blood viscosity on the hyperdynamic circulation, portal pressure, and vascular geometry.

Blood Viscosity and the Complications of Diabetes
1984Increased viscosity in diabetes mellitus was forst noted by Skovborg et al. (1966) and has since been confirmed by several groups including Isogai et al. (1976) and Barnes et al. (1977) although the results are somewhat conflicting. These studies have mostly been carried out in older diabetics in whom the presence of atherosclerosis may cause secondary

Capillary blood viscosity in microcirculation.
Clinical hemorheology and microcirculation, 2006As known, at the arteriolar level there is the highest resistance to the flow due to the section and to the velocity with an average pressure fall of 50 mmHg (from 85 to 35 mmHg). This resistance is expressed in sec(-1) by the ratio W/2r. This ratio is very high with an average value of 332 sec(-1) and viscosity at this high shear-rate is negligible ...

The blood viscosity depends on the number of the corpuscular elements pres e n t ?and on the viscosity of the plasma. It is rapidly altered by conditions which concentrate or dilute the fluid of the blood, and is very sensitive to slight variations in the carbon dioxide.
