WebRecent reports have shown that venous hypercarbia, resulting in a widening of the veno-arterial difference in PCO2 (dPCO2), is related to systemic hypoperfusion in various forms of low-flow state. Although septic shock usually is a hyperdynamic state, other factors can influence the CO2 production and elimination, and thus dPCO2 in septic shock ... Web27 de abr. de 2024 · The mean pCO2 values of all patients were found to be 42.4 ± 8.6 mmHg, and the mean of ETCO2 values were 36 ± 7.5 mmHg. A significant correlation was found between the pCO2 value and ETCO2 value. In addition, it was emphasized that ETCO2 was so inconsistent that it could not be used instead of pCO2 [ 13 ].
