What Quantity of Oxygen Would Be Transported If Hb Was

Question

What quantity of oxygen would be transported if Hb was 12g% and the SaO2was 90%?
A) 14.47 vol% O2
B) 19.8 vol%
C) 16.98 vol%
D) 16.08 vol% O2

Accepted Answer

The amount of oxygen transported is calculated using the formula: Oxygen content = (Hb g/dL * 1.34 mL O2/g Hb * SaO2) + (PaO2 * 0.003). Given Hb is 12g% and SaO2 is 90%, the dissolved oxygen part (PaO2 * 0.003) is negligible for this calculation, so we focus on the bound oxygen. Thus, (12 * 1.34 * 0.90) = 14.472, which rounds to 14.47 vol% O2, making option A correct.
