Good point. It is not so much the atmospheric partial pressure of CO2, but
the rate that the bodily CO2 is expired. My understanding is that in the
Hb, raising the partial pressure of O2 will increase the Hb exchange of CO2
What has always confused me, is that surely with applied oxygen, the persons
respiration rate will decrease accordingly.....
