Analysis of the Interrelationships of Non-Nutrient Blood Flow, Oxygen Delivery, Oxygen Consumption, and the Ratio of Oxygen Delivery/Oxygen Consumption Based on a Mathematical Model of Non-Nutrient Blood Flow
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.
