Frequently Asked Questions
What is a normal urine output?
In adults, a normal output is generally > 0.5 mL/kg/hr. For children, it is typically > 1.0 mL/kg/hr.
What is oliguria?
Oliguria is defined as urine output less than 0.5 mL/kg/hr in adults for more than 6 hours.
Why use mL/kg/hr instead of total volume?
Weight-based calculation allows for a consistent standard across different body sizes, insuring a 50kg person and a 100kg person are both evaluated fairly.
