Sodium Correction Rate CalculatorCanineFeline

Calculate safe sodium correction rate for dogs and cats with hyponatremia or hypernatremia. Determines the sodium deficit or excess, recommended correction time, and hourly correction rate to stay within the safe limit of 0.5 mEq/L/hr (max 10–12 mEq/L per 24 hours). Rapid correction of chronic sodium disorders can cause osmotic demyelination syndrome (hyponatremia) or cerebral edema (hypernatremia). Used for dysnatremia management, fluid therapy planning, free water deficit calculation, critical care electrolyte correction, and sodium monitoring in CKD, Addison’s disease, GI losses, and psychogenic polydipsia. Common queries: 'sodium correction rate for a dog', 'how fast to correct hyponatremia', 'hypernatremia treatment plan', 'safe sodium correction veterinary'.
