Relation Between Central Venous, Peripheral Venous and Arterial Lactate Levels in Patients With Sepsis in the Emergency Department

Figures

Figure 1.
Figure 1. Box-plot diagrams comparing arterial versus central vein versus peripheral vein lactate levels. There are no significant differences between the three sample sites.
Figure 2.
Figure 2. Linear regression analysis: peripheral blood lactate is a strong, highly significant but imperfect predictor of arterial blood lactate (r = 0.88, P < 0.001) (a), peripheral vein lactate is a strong, highly significant but imperfect predictor of central vein lactate (r = 0.94, P < 0.001) (b), and central vein lactate is a strong, highly significant but imperfect predictor of arterial blood lactate (r = 0.90, P < 0.001) (c).
Figure 3.
Figure 3. Bland-Altman plot shows good agreement between central vein lactate and peripheral vein lactate (a), between central vein lactate and arterial blood lactate (b) and between arterial blood lactate and peripheral vein lactate (c).
