Tables for estimating dilutional hematocrits and blood flow rates from total blood volume and body surface area formulae

This paper provides a historical look at the development of formulae for predicting body surface area and total blood volume. A variety of experimental methods used for the development of body surface area and total blood volume formulae are briefly reviewed. The varying results of different formulae and nomograms are considered in relation to their impact on calculations typically used for the cardiopulmonary bypass patient. Charts are provided which will aid the clinician in the determination of body surface area, relative perfusion output, total blood volume, and resultant hematocrit.
