Critical Hematocrit in Intestinal Tissue Oxygenation during Severe Normovolemic Hemodilution

Abstract

Intestinal microPO2 and VO2 were limited by a critical decrease in DO2 and hematocrit at the same time. Beyond these critical points not only shunting of oxygen from the microcirculation could be demonstrated, but also a significant correlation between intestinal microPO2 and VO2.
