Figure 2From: Oxygen consumption is depressed in patients with lactic acidosis due to biguanide intoxicationRelation between systemic oxygen consumption and lactatemia in biguanide-intoxicated patients. Systemic oxygen consumption (VO2), computed from either mixed (black circles) or central (white circles) venous oxygen saturation, inversely correlated with plasma lactate (R2 = 0.43; P < 0.001; n = 32).Back to article page
