John,

I have the utmost respect for your knowlege in this stuff,
but, John, this is not what folks say in any course I've ever heard
of.  

Increased partial pressures mean driving the hemoglobin binding 
reaction harder.  Unless you have found that accordingly higher, in
the same proportion, naturally, as pressure increases, come to think
about it, p02's keep it in the same balance.  So, then, are you saying
that the steady-state balance of hemoglobin binding sites for the two 
guilty parties (CO and O2) does not change since their relative partial
pressures do not change?  This opposes what I have heard some pretty
well known scuba-folks say.

You know, I just sat here and almost talked myself into this.
