Abstract

THE concentration of red cells is not the same in all parts of the circulatory system¹, the cell plasma ratio being lower in the capillaries and small vessels than in the larger arteries and veins. The over-all cell percentage (body hæmatocrit) is determined from the direct measurement of both red cell volume and plasma volume, and from this the body/venous hæmatocrit ratio (BH/VH ratio) is calculated. In normal adults resident at sea-level the BH/VH ratio averages 0.91 (ref. 2).
