When CO2 increases in a tissue, pCO2 would be higher , so pO2 should be less, but the curve 'shifts to the right'. That means PO2 increases . there is a paradox here I don't understand . Can SB explain it ?

 

thank you!

That isn't what a shift to the right means, the shift means that a higher partial pressure of O2 is need to create a 50% saturation rate of foetal haemoglobin, and what self respecting scientist creates a graph that looks like that. :P
