Electrolyte replacement calculator
Calculate electrolyte deficit and replacement rates for potassium, sodium, and chloride in dogs and cats. Includes safety limits and monitoring guidance. Educational decision-support tool only.
Safety checks
- This tool supports calculation and education only.
- It does not diagnose, prescribe, or replace clinical judgment.
- Rapid electrolyte correction can cause serious complications.
- Always verify calculations and patient-specific factors.
- Monitor cardiac rhythm during potassium replacement.
Basis and limits
- Potassium deficit: mEq = 0.3 × kg × (desired − current). Max 0.5 mEq/kg/hr peripheral, 1.0 mEq/kg/hr central with monitoring.
- Sodium deficit: mEq = 0.3 × kg × (desired − current). Correct chronic hyponatremia at < 0.5 mEq/L/hr.
- Chloride deficit: mEq = 0.2 × kg × (desired − current). Often corrects with sodium replacement.
- Scope: this tool provides arithmetic support. It does not replace clinical assessment or monitoring.
