Sodium Deficit in Hyponatremia
Estimates the amount of sodium deficit using total body water, current serum sodium, and desired serum sodium.
Enter weight in kilograms.
mEq/L or mmol/L.
mEq/L or mmol/L. Keep target clinically appropriate.
Estimated Sodium Deficit
Formula: Sodium deficit = TBW factor × weight (kg) × (desired sodium − current sodium).
Clinical caution: This is an estimate only. Treatment of hyponatremia depends on symptoms, acuity, volume status, cause, and close lab monitoring. Avoid rapid correction unless directed by a qualified clinician.
