this is really helpful!!! i have a couple more problems. ph-7.48, paco2-32, and hco3-24-is this metabolic alkalosis? also, ph-7.45, paco2-47, and hco3-29-is this metabolic acidosis with partial compensation? thanks!!!
#1 – yes (edit: make that a no. daytonite is correct in her post below - it is respiratory alkalosis. sorry! and thanks daytonite!)
#2 – no
you are correct that it’s a metabolic mechanism, but if hc03 numbers are high is that acidosis or alkalosis?
ph is within normal range. so if ph is within normal range then the compensatory mechanism has done its job and fixed the problem. it’s fully compensated.
(again, this is just barely in range. ph of 7.46 would be technically out of normal range making it partially compensated.
*this is just a technicality for test taking. a ph of 7.45 or 7.46 isn’t going to be much different for an actual pt)
this is the mental tool that i keep in mind.
alk / acid / alk
ph / pc02 / hc03
*ph numbers high = alkalotic
pc02 numbers high = acidic
hc03 numbers high = alkalotic
