Abstract
In mathematical simulation of oxygen transport the diffusion problem is often simplified by several assumptions including that of local chemical equilibrium and of negligible augmentation of oxygen transport by oxyhemoglobin diffusion. In the present work the applicability of the various assumptions is investigated by numerical solution of the equations governing transient diffusion and reaction in hemoglobin layers. The fluxes, and space and time scales are chosen to cover the range of interest in the microcirculation. The results show that significant improvements in accuracy are possible by treatment of a more complete system of equations, and show the relative importance of the various simplifying assumptions.
