Critical Analysis of Venoarterial CO2 Gradient as a Marker of Tissue Hypoxia

  • Conference paper
Yearbook of Intensive Care and Emergency Medicine

Part of the book series: Yearbook of Intensive Care and Emergency Medicine ((YEARBOOK,volume 1996))

Abstract

The venoarterial carbon dioxide (CO2) tension (PCO2) gradient (ΔPCO2 ) is the difference between PCO2 in mixed venous blood (PvCO2) and PCO2 in arterial blood (PaCO2):

$$ \Delta {\text{PC}}{{\text{O}}_{{\text{2}}}}{\mkern 1mu} = {\mkern 1mu} {\text{PvC}}{{\text{O}}_{{\text{2}}}}{\mkern 1mu} - {\mkern 1mu} {\text{PaC}}{{\text{O}}_{{\text{2}}}} $$

PaCO2 and PvCO2 are partial pressures of the dissolved CO2 in arterial and mixed venous blood, respectively, which represent only a fraction of arterial CO2 content (CaCO2) and mixed venous CO2 content (CvCO2), respectively.
