Hematocrit and risk of NIDDM

Diabetes, 1996
There is limited evidence that raised hematocrit levels may be associated with insulin resistance, which links cardiovascular disease with NIDDM. The association between hematocrit level at screening and the subsequent development of physician-diagnosed NIDDM during 12.8 years of follow-up was examined in a prospective study of 7,735 middle-aged men ...

Hematocrit measurement by dielectric spectroscopy

Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2002
Based on permittivity changes, a new method to measure hematocrit (HCT) in extracorporeal blood systems is presented. Human blood samples were tested at different HCT levels pairing the values of permittivity change, obtained by means of a commercial impedance analyzer, with traditional centrifugation measurements.

WHOLE BODY HEMATOCRIT: LARGE VESSEL HEMATOCRIT RATIO IN HYPERTENSION

Acta Medica Scandinavica, 1968
AbstractWhole body hematocrit/large vessel hematocrit (WBH/LVH ratio) has been examined in 21 normotensive and 35 hypertensive subjects and found to be the same, presumably as an expression of a uniform distribution of the blood volume in the two groups.

Optimal hematocrit for hemodialysis

Current Opinion in Nephrology and Hypertension, 1997
Considerable controversy continues over the optimal hematocrit target for dialysis patients being treated with recombinant erythropoietin. Recent short-term studies have demonstrated a significant improvement in brain function when hematocrit is 42% compared with when it is 31%.

Raptor Hematocrit Values

The Condor, 1980
perimental and control adults fed similar proportions of fish, garbage and intertidal food to their young. Although the young of experimental adults gained weight normally, the adults may have lost more weight than control adults and so lessened their own chances of survival. This possibility could not be investigated.

Microcirculatory hematocrit and blood flow

Journal of Theoretical Biology, 1988
Direct measurements from many laboratories indicate that the oxygen tension in skeletal muscle is significantly less than in the large veins draining these tissues. Harris (1986) has proposed that because of the parallel anatomic arrangement of large arterioles and venules in skeletal muscle, a counter-current exchange between these vessels can occur ...

Optimal hematocrit theory: a review

Journal of Applied Physiology
In humans and many animals, a trade-off between a sufficiently high concentration of erythrocytes (hematocrit) to bind oxygen and sufficiently low blood viscosity to allow rapid blood flow has been achieved during evolution. The optimal value lies between the extreme cases of pure blood plasma, which cannot practically transport any oxygen, and 100 ...

AN HEMATOCRIT METHOD

JAMA: The Journal of the American Medical Association, 1925
The hematocrit is an instrument by which is determined the volumetric relationship between corpuscles and plasma in a specimen of blood. Separation of the two elements is brought about in the centrifuge by virtue of a difference in their specific gravities.
