I just had a test and have a question on an acid-base interpretation that we had to do.
Here are the ABGs:
pH 7.45
CO2 30
HCO3 32
Both CO2 and HCO3 is showing an alkalotic state. Is this respiratory alkalosis or metabolic alkalosis??...with full compensation.
Please help~! Thanks!!

Is this all the information you were given?
Yes. We had to interpret this as respiratory or metabolic, alkososis/acidic or neither, full or partial compensation.
It doesn't make sense because both CO2 and bicarbonate are showing alkolosis. I wrote full compensation since it is at 7.45. But not sure if this is metabolic or respiratory.

http://www.medcalc.com/acidbase.html says:
(1) partially compensated primary respiratory alkalosis, or
(2) acute superimposed on chronic primary respiratory alkalosis, or
(3) mixed acute respiratory alkalosis with a small metabolic acidosis
pH > 7.48 and HCO3 > 22, for acute (uncompensated)
pH
expected pH = 7.65
expected CO2 = 47
expected HCO3- = 20
Other calculators called it a mixed disorder. Post the explanation, if you get one.
