I could cite somewhat more traditional sources, but Creighton was right, elevated CO2 does alter blood pH levels. Whether CO2 elevation plays a role in RBC rigidity, however intuitive, isn't established by anything I've yet read. I'll keep looking. Were it to be established, it might support the notion that increased physical conditioning and lowered work of breathing would lower CO2 levels, reduce pH disturbance and dampen the impact on RBC rigidity. That's connecting a lot of dots and I don't even know if this thinking is the logic behind the WKPP's case about PN2's, or, rather, the efficacy of substituting He for N2, and rigidity.
It would be really nice if someone on here who actually knows something about hemorheology would add to the discussion. I feel like a lab rat in a maze.
I'll also admit to real fatigue over the sniping discussion of JW's atheistic relationship with footnotes.
