Follow our detailed instruction and the urine output calculation examples:
- Collect your patient's weight, age, urine output, and the period over which the urine was collected. Our patient is 20 years old, weighs 80 kg, and we collected 3L (3000 mL) of urine during a 24-hours observation period.
- Use the following equation to compute how much urine is output per hour: Urine output (ml/kg/hr) = Collected urine / (Weight * Time)

How do you calculate adequate urine output?
Calculate urine output per hour by dividing each kilogram of body weight by 0.5 milliliters, according to EasyCalculation.com. This is the minimum expected hourly urine output for an average adult. For children, the expected output per hour is about 1 milliliter per kilogram of body weight. Urine consists mostly of water, along with salts ...

Oliguria is a medical term for low urine output (how much you pee). In the case of an adult, this means less than 400 milliliters (mL) to 500 mL (around two cups) of urine per 24 hours. The numbers depend on weight in terms of children and infants.
What is considered high urine output?
An excessive volume of urination for an adult is more than 2.5 liters (about 67 fluid ounces or about 2.6 quarts) of urine per day. However, this can vary depending on how much water you drink and what your total body water is. This problem is different from needing to urinate often.

What is the ability to accurately measure and record urine output?
The ability to accurately measure and record urine output is a key clinical skill all healthcare professionals should possess. The rate of urine output can provide insights into how well the kidneys and other organs are being perfused, allowing for early recognition of deteriorating patients (e.g. sepsis, haemorrhage).
How does a catheter work?
Some catheters have a single bag which all urine drains into immediately, whereas others have a separate chamber that urine drains into first. This first chamber can then be emptied by opening the valve, allowing the urine to move into the larger catheter bag.

If the catheter bag is full, this should be emptied after your recording. If the patient has a separate urine collection chamber device, the valve should be opened to allow the chamber to empty into the catheter bag and the valve should then be closed.
