The sodium correction rate in hyponatremia and hypernatremia calculates recommended fluid type, rate, and volume to correct hyponatremia slowly (or more rapidly if seizing).
To calculate recommended fluid type, rate, and correction volume.
Use to calculate recommended fluid type, rate, and correction volume. Formula: Fluid rate, mL/hr = (1000 x rate of sodium correction, mmol/L/hr) / change in serum sodium Where: Change in serum sodium = (fluid sodium, mmol/L - serum sodium, mmol/L) / (total body water + 1) Total body water = weight, kg x % body water, defined as follows: % body water: Age Male Female Child 0.6 0.6 Adult 0.6 0.5 Elderly 0.5 0.45
