Figure 1From: Skeletal muscle oxygen saturation does not estimate mixed venous oxygen saturation in patients with severe left heart failure and additional severe sepsis or septic shockCorrelation between skeletal muscle StO2 and SvO2. Group A includes patients with severe left heart failure without severe sepsis/septic shock, and group B includes patients with primary heart disease and additional severe sepsis/septic shock. A statistically significant correlation was found in group A (r = 0.689, P = 0.002) but not in group B (r = -0.091, P = 0.60). StO2, tissue oxygenation; SvO2, mixed venous oxygen saturation.Back to article page
