Potassium Supplementation CalculatorCanineFeline

Calculate IV potassium chloride (KCl) supplementation for hypokalemic dogs and cats using the standard veterinary sliding scale. Determines the amount of KCl (mEq) to add per liter of IV fluids based on serum potassium level, and computes the maximum safe infusion rate. Based on the Merck Veterinary Manual supplementation guidelines and AAHA fluid therapy guidelines. Covers severe hypokalemia (< 2 mEq/L) through mild hypokalemia. Maximum safe IV potassium rate is 0.5 mEq/kg/hr. Used for hypokalemia treatment, fluid therapy potassium supplementation, electrolyte correction, CKD potassium management, diabetic ketoacidosis electrolyte replacement, and post-obstruction potassium monitoring. Common queries: 'potassium supplementation sliding scale', 'how much KCl to add to fluids', 'hypokalemia treatment dog'.
