## How do you calculate 24 hour fluid maintenance?

## How do you calculate fluid intake and output?

The formulas used are: Urine output in mL/kg/hr = Total urine output in mL / (Weight in kg x Hours); Fluid balance in mL = Fluid intake in mL – Total urine output in mL. In healthy adults, normal values for total urine output are 800 – 2000 mL (considering a fluid intake of 2 L and a period of 24h).

## Why am I on a fluid restriction?
