Q

Equation for total blood oxygen content

A

Total blood O2 content = (SO2 x ceHb x BO2) + (PaO2 x 0.03)

ceHb - effective Hb conc
PaO2 - partial pressure oxygen in arterial gas
0.03 - content in mL/L/mmHg of dissolved oxygen in blood
BO2 - max amount of Hb-bound O2 per unit volume of blood, normally 1.39
SO2 - oxygen saturation
