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)
