Figure 2

Shows the close correlation between GFR and renal QO2 in uncomplicated post-cardiac surgery patients (controls, n= 37)) and in patients with postoperative acute kidney injury (AKI). Note that the slope of the regression line is steeper in the AKI group. Thus filtration and reabsorption of sodium consumes approximately 2.5 times more oxygen in the AKI group.
