DKA Severity Calculator Result

--
FormulaStratification based on worst parameter. Severe: pH <7.00, HCO3 <10, or Stupor/Coma. Moderate: pH <7.24, HCO3 <15, AG >12, or Drowsy. Mild: pH <7.30, HCO3 ≤18, AG >10, Alert.

Clinical Pearls

Guides the intensity of care and resource allocation. Severe DKA has a higher risk of complications (e.g., cerebral edema, arrhythmias, cardiovascular collapse).

Limitations

Assumes positive urine/serum ketones are present. Venous pH can generally be used in place of arterial pH (it is typically 0.03 lower than arterial).
