Hemoglobin (Hb) can react with both O2 and CO2 at 37 C. The reaction below demonstrates how CO can displace O2 from hemoglobin with a K=2.0 x 102.
HbO2 (aq) + CO(g) <===> HbCO (aq) + O2(g)
If the ratio [HbCO]/[HbO2] coms close to 1, death will happen. Explain what partial pressure of CO is fatal? Presume the partial pressure if O2 is 0.20atm
