Red Cell and Plasma Volume in Newborn Infants

Abstract

In Figs. 1-4 the term " venous haematocrit " is used for an estimate of the true volume of red cels in unit volume of venous blood; this estimate is based on the formula: (P.C.V. -2) . 95, where P.C.V. = total packed cell volume in the venous haematocrit. - is an average correction for leucocytes and x 95 is a correction to account for trapped plasma. 250 ,
