Hypertonic Saline (3%) calculator
Disclaimer

Hypertonic saline is usually reserved for severe hyponatremia (sodium < 115 meq/L). This calculator targets a level of 120 or 125 meq/L and determines the rate necessary to increase the serum sodium at 0.5 meq/L/hr.  Look here for a review of hyponatremia. In severe cases, the maximum sodium increase within the first 24 hours should not exceed 10 to 12 meq/liter in order to reduce the risk of CNS lesions and/or pulmonary edema.
