The result of the model calculations are presented in a table given in the appendix for a range of "Hi" from 0.30 to 0.50 with ANH performed to minimum hematocrits from 0.30 to 0.15. Given a "Hi" of 0.40, if the "Hm" is assumed to be 0.25.then from the equation above the RCM count is still high and ANH is not necessary, if BLs does not exceed 2303 ml, since the hemotocrit will not fall below Hm, although five units of blood must be removed during hemodilution. Under these conditions, to achieve the maximum benefit from the technique if ANH is used, no homologous blood will be required to maintain the "Hm" if blood loss does not exceed 2940 ml. In such a case ANH can save a maximum of 1.1 packed red blood cell unit equivalent, and homologous blood transfusion is necessary to maintain "Hm", even if ANH is used.
