Figure 1From: Another explanation for decreased oxygen consumption in lactic acidosisEffect of metformin and lactic acid on arterial pH and oxygen consumption. Upper panel: data recorded from a pig infused with 8 g metformin (final serum drug concentration, 98 μg/ml). Lower panel: data recorded from a pig infused with lactic acid. Lactatemia equally increased from 1 to 25 mmol/l in the two animals. VO2, oxygen consumption.Back to article page
