Figure 3.

Concordance between changes in SvO₂ and changes in thenar muscle StO₂ in the absence of severe sepsis/septic shock. Shown are changes in SvO₂ and thenar muscle StO₂ in 10 patients with severe left heart failure without additional severe sepsis/septic shock (group A; n = 40, r = 0.836, R² = 0.776, P < 0.001; equation of the regression line: ΔSvO₂ [%] = 0.84 × ΔStO₂ [%] - 0.67). StO₂, tissue oxygenation; SvO₂, mixed venous oxygen saturation.
