Central venous-to-arterial carbon dioxide difference combined with arterial-to-venous oxygen content difference (PcvaCO2/CavO2) reflects microcirculatory oxygenation alterations in early septic shock

ConclusionsIn a population of early septic shock patients, increases in PcvaCO2 and PcvaCO2/CavO2 reflected different alterations at the microcirculatory level. While PcvaCO2 was related to global flow, the PcvaCO2/CavO2 ratio was associated to impaired local oxygen utilization and diminished microvascular reactivity.
