When interpreting ABG's you first look at the Ph. It should be 7.35-7.45. If it is above 7.45 it is alkalotic. Think about the "K" in this word.(kick up the Ph). If it is below 7.35 is is acidotic(think about the "D") it means sown the PH. Next you look at the PCO2 and the HCO3. The PCO shoule be between 32-45. The Hco3 should be between 20-26. Depending on whether they're up or down brings you to the final step. If they are opposites it's Respiratory. If it is equal it is metabolic.
The Mnemonic to remember is RO(respiratory,opposites) or ME (metabolic equal) ROME
