Question

From the shunt equation, given that the shunt ratio, Qs/Qt, is 0.20, calculate the arterial O2 content if the PAO2 is 104 and the CcO2 is 20 ml O2/100ml blood, and the CvO2 is 14 ml O2/100ml blood. Now, using the hemoglobin saturation curve, estimate the SaO2 and the PO2 for the content you just calculated. What is the DAaO2, i.e. the difference between PO2 in the alveoli and artery? Notice that you should find a pretty large DaAO2 for a fairly small content difference due to the flatness of the Hb saturation curve at high O2

Explanation / Answer

RQ = [V(dot)CO2]/[V(dot)O2]
