Figure 3From: Clinical use of lactate monitoring in critically ill patients1,745 combined measurements of arterial pH and arterial lactate in 171 critically ill patients. Horizontal and vertical lines represent suggested definition of lactic acidosis [8]. For lactate levels ≥ 5.0 mmol/L, a significant linear regression analysis reveals a R2 = 0.28 (p < 0.001).Back to article page
