DKA Resolution Criteria

Applies the published criteria for resolution of diabetic ketoacidosis.

Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.

Example

Glucose, mg/dL
180 mg/dL
Serum bicarbonate, mEq/L
16 mEq/L
Venous pH
7.34
Anion gap, mEq/L
10 mEq/L

Result: resolved: a glucose of 180 with 3 of the three met

The tool opens with these values already filled in. Replace them with your own.

What the result means

Resolved
A glucose below 200 mg/dL together with at least two of a bicarbonate at or above 15 mEq/L, a venous pH above 7.30, and an anion gap at or below 12 mEq/L.
Not the glucose
A normal glucose is one of four conditions. Stopping the infusion when it falls is the commonest way rebound ketoacidosis happens: the infusion closes the gap, and the glucose falls first.
Two of three
Not all three. A patient whose gap and bicarbonate have come back still qualifies while the venous pH lags, because resuscitation fluid leaves a hyperchloremic acidosis behind.
A closed gap alone
One of three, and not enough on its own.
The anion gap, not ketones
The nitroprusside reaction misses beta-hydroxybutyrate, the dominant ketone early, so measured ketones can appear to rise as a patient improves.
After resolution
Subcutaneous insulin is given and overlapped with the infusion, conventionally by 1 to 2 hours, before the infusion comes down.

What you enter

  • Glucose, mg/dL (resolution needs it below 200)
  • Serum bicarbonate, mEq/L (met at 15 or above)
  • Venous pH (met above 7.30)
  • Anion gap, mEq/L (met at 12 or below; this is the variable that tracks the ketosis)
