How to Use DKA Calculator
DKA Calculator is built to screen for a simplified DKA severity pattern using glucose, ketones, pH, bicarbonate, sodium, and potassium. Focus first on the inputs that directly drive the calculation:
- Enter the core measurement — Enter glucose in mg/dL and ketones in mmol/L.
- Check units and options — Enter blood pH and bicarbonate because these determine acidosis severity.
- Read the primary result — Enter sodium and potassium to display corrected sodium and electrolyte context.
- Review supporting values — Read the DKA classification together with corrected sodium and ketone status.
Formula & Theory - DKA Calculator
DKA Calculator uses this core formula:
DKA_pattern = glucose ≥ 250 and ketones ≥ 3 and (pH < 7.30 or bicarbonate < 18)
corrected_sodium = measured_sodium + 1.6 × max((glucose - 100) ÷ 100, 0)
severity = compare(pH and bicarbonate with mild, moderate, severe bands)The DKA Calculator follows the requested ADA-style logic: hyperglycemia, ketosis, and acidosis must be considered together. Severity is then driven mainly by pH and bicarbonate.
DKA is a medical emergency. Mental status, anion gap, osmolality, infection, pregnancy, renal function, potassium replacement, insulin, and fluids require clinical protocols.
Before interpreting DKA Calculator, confirm glucose is in mg/dL, ketones are in mmol/L, and pH or bicarbonate values are current enough for severity review.
Use Cases for DKA Calculator
DKA Calculator is most useful in these situations:
- Emergency medicine teaching.
- Metabolic case review.
- Explaining why ketones and acidosis matter beyond glucose.
- Checking corrected sodium in a DKA scenario.
