The resistance to diffusion of 02 through the wall is neglected.
If the plasma undergoes Poiseuille flow, then it is possible to calculate, from equation
24 of the Appendix, the per cent saturation of the plasma at any point along
the capillary. Let us take a capillary diameter of 10 microns, an average velocity
of 0.1 cm/sec., and a diffusion constant for oxygen through plasma of 2 x 10-5
cm2/sec. (cf. reference 12). The average per cent saturation of the plasma in
