▁of ▁ 7 0   ml / kg ▁( 4 9 0 0   ml ). ▁A ▁range ▁of ▁Hi ▁and ▁H m ▁was ▁evaluated ▁to ▁understand ▁conditions ▁where ▁hem od il ution ▁is ▁necessary ▁to ▁benefit ▁the ▁patient . ▁ ▁Result ▁The ▁result ▁of ▁the ▁model ▁calculations ▁are ▁presented ▁in ▁a ▁table ▁given ▁in ▁the ▁append ix ▁for ▁a ▁range ▁of ▁Hi ▁from ▁ 0 . 3 0 ▁to ▁ 0 . 5 0 ▁with ▁AN H ▁performed ▁to ▁minimum ▁h emat oc rit s ▁from ▁ 0 . 3 0 ▁to ▁ 0 . 1 5 . ▁Given ▁a ▁Hi ▁of ▁ 0 . 4 0 , ▁if ▁the ▁H m ▁is ▁assumed ▁to ▁be ▁ 0 . 2 5 . then ▁from ▁the ▁equation ▁above ▁the ▁R CM ▁count ▁is ▁still ▁high ▁and ▁AN H ▁is ▁not ▁necessary , ▁if ▁B L s ▁does ▁not ▁exceed ▁ 2 3 0 3   ml , ▁since ▁the ▁hem ot oc rit ▁will ▁not ▁fall ▁below ▁H m , ▁although ▁five ▁units ▁of ▁blood ▁must ▁be ▁removed ▁during ▁hem od il ution . ▁Under ▁these ▁conditions , ▁to ▁achieve ▁the ▁maximum ▁benefit ▁from ▁the ▁technique ▁if ▁AN H ▁is ▁used , ▁no ▁hom olog ous ▁blood ▁will ▁be ▁required ▁to ▁maintain ▁the ▁H m ▁if ▁blood ▁loss ▁does ▁not ▁exceed ▁ 2 9 4 0   ml . ▁In ▁such ▁a ▁case ▁AN H ▁can ▁save ▁a ▁maximum ▁of ▁ 1 . 1 ▁pack ed ▁red ▁blood ▁cell ▁unit ▁equivalent , ▁and
