Arterial blood gas showed my pO2 was HIGH at 103. How is this possible? I'm not on oxygen therapy or anything like that. I was breathing normally.

High PO2 level. It is important to know the rest of the blood gas test results. pH? pCO2? Bicarbonate? Your doctor can put it all in perspective for you. What was the O2 sat? If low, it might point to a methemoglobinemia, perhaps from some meds you take. Best to discuss the entire blood gas study with your provider. Normal PO2 shouldn't be above 102. . .

Can high o2 affinity hemoglobin cause arterial blood gas values of high o2?

Less O2 delivery. High o2 affinity HGB (leftward shift in o2 saturation curve) means it requires a higher partial pressure of o2 to achieve the same o2 saturation. The HGB is more tightly bound to o2 and less is delivered to the tissues. More o2 will be necessary to adequately deliver oxygen to the tissues. Read more...

How would oxygen deprivation change arterial blood gas levels?

Breath rate increase. O2 deprivation will typically cause people to breath faster. Abg measures levels of oxygen, carbon dioxide and blood ph. Faster breathing causes a drop in co2 which then causes the blood to have an increase in ph (towards basic, not acidic). Over time, the body would compensate for this ph change via acid retention by the kidney and although the co2 would remain low, the ph would approach normal. Read more...
