Look at pH (acidosis - low or alkalosis - high) 2. Check the CO2 (resp. indicator) - less than 35 (alkalosis) more than 45 (acidosis) 3. Check the HCO3 (metabolic indicator) - less than 22 (acidosis) more than 26 (alkalosis) 4. Determine primary disorder (matches the pH) 5. Determine if its compensated (pH returns to normal or near normal)
