Bicarbonate deficit calculator

Estimate a bicarbonate amount from clinician-entered acid-base values. It does not determine an indication, preparation, route, rate, or treatment plan.

Educational calculation only. Verify with current acid-base data and licensed veterinary judgment.
Safety checks
  • This tool supports calculation and education only.
  • It does not diagnose an acid-base disorder or determine whether bicarbonate is indicated.
  • Use current blood-gas assessment and licensed veterinary judgment to select any target.
  • It does not provide a concentration, volume, route, rate, partial-correction amount, or treatment plan.
Basis and limits
  • Formula: estimated amount (mEq) = 0.3 L/kg × (target HCO₃⁻ − patient HCO₃⁻) × body weight (kg).
  • Reviewed assumptions: the volume of distribution is approximately 0.3 L/kg; the entered target must be 10–15 mEq/L.
  • Scope: this is transparent arithmetic only. It does not diagnose, determine an indication, establish a dose plan, or replace serial blood-gas assessment.
  • Reference: Merck Veterinary Manual: Rule of 20, acid-base balance.
