Step One:

- correct hypovolemia first if any signs of low flow rate is present (e.g., low BP or urine output)

Step Two:

- calculate normal TBW

- TBW = 0.6 L/kg x weight in kg (children and males <70 yo)

- use 0.5 L/kg in men >70 and females <70 yo

- use 0.45 L/kg for women >70 yo

- use 0.4 L/kg for dehydrated, older patients

Step Three:

- calculate current TBW

- current TBW = normal TBW x (140/serum Na⁺)

Step Four:

- calculate water deficit

- water deficit (L) = normal TBW - current TBW

Step Five:

- determine replacement fluid and total volume of the replacement fluid

**max recommended sodium correction rate is 0.5 mEq/L/h
