        Acute: Increase in HCO3 by 0.1 x change in PaCO2
        
        Chronic: Increase in HCO3 by 0.4 x change in PaCO2
  - - - AG = Na - (Cl + HCO3) (Corrected for Albumin: every change in albumin by 1g/dL = change in AG by 2.5)

        Diarrhea, Fistulas, NS infusion, RTAs
        
        Expected Compensation: PaCO2 = (1.5xHCO3) + 8 +/- 2
        
        Delta/Delta: Comparing change in AG and change in HCO3. Easiest way to calculate: Calc HCO3 = (AG-12) + HCO3. If Calc HCO3 >24 = also met alk. If Calc HCO3 < 24 = also Non-ag met acid
- - - - Acute: Increase in HCO3 by 0.2 x change in PaCO2
      - Chronic: Increase in HCO3 by 0.4 x change in PaCO2

        Expected Compensation: PaCO2 = 0.75 x change in HCO3
