Abstract

Non-nutrient blood flow (NNBF) is defined for the purposes of this model as any blood flow that does not participate in oxygen exchange at the level of the microcirculation. It theoretically includes intra-cardiac and large vessel left to right shunts, anatomic and physiologic shunting in the microcirculation, decreased cellular utilization of oxygen, and decreased diffusion of oxygen.
