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
