Key result
Central venous oxygen saturation (ScvO2) is not interchangeable with mixed venous oxygen saturation (SvO2) during and after cardiac surgery, demonstrating a mean bias of 4.4% (95% CI -13.6 to 22.3).

ScvO2 should not substitute for SvO2 in cardiac surgery monitoring; challenges equivalence assumptions and leaves open validation of optimal targets.

Does continuous measurement of ScvO2 accurately reflect SvO2 in patients during and after elective cardiac surgery?
Mean Difference: 4.4 (95% CI -13.6–22.3)
Continuous measurements of central venous oxygen saturation (ScvO2) and mixed venous oxygen saturation (SvO2) show considerable variability and cannot be used interchangeably in cardiac surgery patients.
Sekkat et al. (2009) conducted an observational in Elective cardiac surgery (n=15). Central venous oxygen saturation (ScvO2) monitoring vs. Mixed venous oxygen saturation (SvO2) monitoring was evaluated on Agreement between ScvO2 and SvO2 (Bland-Altman analysis) (Mean bias 4.4%, 95% CI -13.6 to 22.3). Central venous oxygen saturation (ScvO2) is not interchangeable with mixed venous oxygen saturation (SvO2) during and after cardiac surgery, demonstrating a mean bias of 4.4% (95% CI -13.6 to 22.3).
