Simplifying the Description of Tissue Oxygenation

Abstract

Here as in all engineering problems first priority must go to establishing orders of magnitude, both of key system parameters and of unavoidable uncertainties. Once this is done it is possible to develop a solution providing the maximum degree of simplicity consistent with the need for accuracy. Accordingly we begin by defining a model, the modified Krogh tissue cylinder of Fig. 1, and establishing representative dimensions and other characteristics (see Fig. 1 and Table 1).
