From: Venoarterial PCO2-to-arteriovenous oxygen content difference ratio is a poor surrogate for anaerobic metabolism in hemodilution: an experimental study

Relationship between oxygen transport to venoarterial PCO2 difference (Pv–aCO2) (a), venoarterial CO2 content difference (Cv–aCO2) (b), and arteriovenous O2 content difference (Ca–vO2) (c). Hemodilution produced opposite effects on Pv–aCO2 and Cv–aCO2. Cv–aCO2 decreased in hemodilution and increased in hemorrhage. These changes are the underlying explanation for different behavior of Pv–aCO2/Ca–vO2 in both groups
