To calculate the rate of urine output, divide the volume of urine produced by the number of hours that have elapsed since the bag/chamber was last emptied (e.g. 80ml over 2 hours = 40ml/hour).

How is daily urine output measured?

1. On day 1, urinate into the toilet when you get up in the morning.
2. Afterward, collect all urine in a special container for the next 24 hours.
