I hope this isn't a silly question, but I'm a new grad on orientation in an ICU and I am having trouble understanding this concept.
So the CO2 level that is given on a BMP isn't actually a measure of CO2, its an indirect measure of bicarb? Why is this? why aren't the CO2 on an ABG and the CO2 on a BMP the same thing?
I tried looking this up but I haven't found anything so I hope someone here can explain to me.
Thanks so much
