The glomerular filtration rate GFR and the renal blood flow RBF correspond to the filtered volume by the kidneys and the blood volume delivered by the renal arteries per unit of time, respectively. A better understanding of renal physiology is needed to delineate the impact of modifications in renal hemodynamics on GFR.

In animals, at the early stages of sepsis, GFR is correlated with cardiac output. In contrast, at later stages, a decline in GFR is observed in animals and humans along with the development of renal vascular damage. The complexity of the mechanisms involved in the relationship between GFR and RBF and the progression in this relationship over time likely explains the repeated failures of hemodynamic interventions in rescuing renal function after end-organ insult.
