Approach

Metabolic acidosis physician extender algorithm
Elevated anion gap? Yes No
Delta-delta (ΔΔ) value Equal to 1 Greater than 1 Less than 1

Definition

  • Delta-Delta value is used to determine whether there is an additional metabolic acid-base disturbance or not.
  • Delta-Delta (ΔΔ) = Delta anion gap (ΔAG) / Delta bicarbonate (ΔHCO3)
    • Delta anion gap (ΔAG) = Calculated anion gap - Expected anion gap
      • Calculated anion gap = [Na+] - [Cl-] - [HCO3-]
      • Expected anion gap = 2.5 x serum albumin level
    • Delta bicarbonate (ΔHCO3) = 24 - serum bicarbonate level
