Figure 3From: Near-infrared spectroscopy during stagnant ischemia estimates central venous oxygen saturation and mixed venous oxygen saturation discrepancy in patients with severe left heart failure and additional sepsis/septic shockCorrelation of mixed venous (SvO 2 ) and central venous saturation (ScvO 2 ) difference with plasma lactate (mmol/L). Pearson correlation 0.400, P = 0.003.Back to article page
