WebI like to think of hemoglobin as the bus whose job is to get the oxygen to the body cells which are low on oxygen. Hemoglobin carries 4 oxygens and holds them the tightest when it has 4, in terms of location in the body this is closest to the lungs (where oxygen is needed the least). ...

WebKelman first gives an equation for the standard dissociation curve (pH=7.4, PCO2=40 mmHg, and Temp=37C), that relates the oxygen saturation (SpO2) and the oxygen tension, PO2 (x): SpO2 = 100 (a1 x + a2 x^2 + a3 x^3 + x^4) / (a4 + a5 x + a6 x^2 + a7 x^3 + x^4).
