I think that's the number you'd get for a standard CBC; it's not the number you'd get from having an arterial blood gas test. That number is a little high and may mean that your body is adjusting to low O2 saturation levels by becoming a little more acidic. Ask your pulmo what she thinks for a clear explanation.

it's easy to confuse the two carbon monoxide and carbon dioxide. A car engine exhausts carbon monoxide we exhale carbon dioxide or methane depending on the exhaust port being used.

I am not sure I seen on my blood test once it was same as yours they never say anything about it. But I do know it’s not good to be in there. At least I think that it’s not good to be in there. I wished I new how to get it out of there. Sorry I couldn’t help. Hugs from Bandit & Momma

Didn't you ask the doctor not that people mind answering but the doctor could probably answer it more indebt . I myself thing everything with COPD is concerning.

After being in this support group with people from all over the world & sharing the different treatments has just taught me everyone & every Dr. is different.Its trial & error.Best of luck to you & keep your spirit up!
