Nearly 15 million units of packed red blood cells and whole blood are transfused annually in the United States alone. Until recently, the major risks from blood transfusion were thought to be transmission of viral infections, and overall, blood transfusion was believed by most providers to be safe.

Stress is believed to increase hematocrit. Groups of patients with generalized anxiety disorders and normal volunteers matched on age and sex were compared on resting levels of state anxiety, trait anxiety, depression, pulse rate, blood pressure and hematocrit.

The purpose of this study is to determine experimentally the optimal incident visible wavelength and light detector angle that yields the maximal change in optical density between an arterial or venous Hct of 20% and 40%. A universal monochromator allows incident wave-lengths in 8-nm increments over the visible range to be selected for the incident ...

Clinical Hemorheology and Microcirculation, 2016
The hematocrit (Hct) determines the oxygen carrying capacity of blood, but also increases blood viscosity and thus flow resistance. From this dual role the concept of an optimum Hct for tissue oxygenation has been derived.

The Role of the Hematocrit in Bleeding
Transfusion Medicine Reviews, 1987Low hematocrit is an often neglected cause in the pathogenesis of a prolonged bleeding time in an anemic patient. There has been ample evidence in the literature, indicating a relationship between hematocrit and the bleeding time; and that the transfusion of RBCs may correct the prolonged bleeding time often observed in anemic patients.

Acoustofluidic hematocrit determination
Analytica Chimica Acta, 2018Hematocrit (HCT) measurements of blood from patients, blood donors and athletes are routinely performed on a daily basis. These measurements are often performed in centralized hospital labs by whole blood analyzers, which leads to long time-to-result.

The Hematocrit of Capillary Blood
New England Journal of Medicine, 1955THE measurement of the packed red-cell volume (or hematocrit) of the venous blood has long been recognized as a useful aid in the study of blood in a large number of clinical conditions.

Optimal hematocrit for hemodialysis
Current Opinion in Nephrology and Hypertension, 1997Considerable 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%.

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, 2002Based 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.
