Sports Medicine, 2003
This review was undertaken, concerning within-subject biological variation and seasonal variation of haematocrit in normal healthy adults and athletes, to find the limits for natural, intra-individual variation in haematocrit values. The terminology and calculations followed well defined theories, from the field of laboratory medicine, about biological

7th International Conference on Appropriate Healthcare Technologies for Developing Countries, 2012
Anaemia is common in clinical practice in tropical Africa where electric haematocrict centrifuges are expensive and electricity from the national grid is unreliable. Two models of manual haematocrit centrifuge have been developed to help in the successful management of patients with anaemia in the tropics. (3 pages)

Hyperoxic ventilation at the critical haematocrit
Resuscitation, 2003During normovolaemic haemodilution arterial O(2)-content decreases exponentially. Nevertheless, tissue oxygenation is first maintained initially by increased organ perfusion and O(2)-extraction. As soon as these compensatory mechanisms are exhausted, myocardial ischaemia and tissue hypoxia occur at an individual 'critical' haematocrit (Hct) value. This

Splenic haematocrit and the splenic plasma pool
British Journal of Haematology, 1987Summary.A method was established for estimation of plasma volume and splenic plasma pool by quantitative scanning using 113mIn labelled transferrin (TF). The method was used in 12 patients with various haematological disorders and degrees of splenomegaly.

Plasma viscosity, haematocrit and red-cell transport
Clinical Physics and Physiological Measurement, 1982An 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

INCREASE IN HAEMATOCRIT IN BORDERLINE HYPERTENSIVE MEN
Clinical and Experimental Pharmacology and Physiology, 1994SUMMARY1. Haematologic parameters were measured in untreated borderline hypertensive (BHT) men, and weight and age matched with normotensive men to determine whether previously described increased haematocrit (Hct) in established hypertension is evident in borderline hypertension.2. Haematocrit was significantly increased in BHT men (mean 0.46, s.d.

Haematocrit in Patients Attending a Hypertension Clinic
Scottish Medical Journal, 1985In view of recent interest in the relationship of haematocrit and blood viscosity to hypertension and vascular disease, we have analysed retrospectively the relationship of haematocrit to blood pressure, vascular complications and other variables in 2,381 patients referred to the Glasgow Blood Pressure Clinic.

Mortality, haemoglobin level and haematocrit in women
Journal of Chronic Diseases, 1985The mortality of 1438 women aged 45-74 from South Wales has been studied from 1967-1978 using techniques of survival analysis to determine whether the haemoglobin level (Hb) or the haematocrit (PCV) are risk factors for death due to ischaemic heart disease (IHD), cerebrovascular accident (CVA) or cancer.

DIURNAL VARIATION IN HAEMATOCRIT VALUE IN PREGNANCY
BJOG: An International Journal of Obstetrics & Gynaecology, 1974SummaryA statistically significant diurnal variation in haematocrit has been observed in pregnant Nigerian women. Under conditions of rest, the haematocrit at 1500 hours averages 0.7 per cent less than at 0900 hours, with some individuals as much as 5 per cent lower.
