The urine output is measured to assess the kidneys status. It is also measured to know the ratio of fluid intake and fluid lost in urine. The method to measure is simple. The urine is made in a measuring bag and when it gets filled up, discarded and another bag is attached. The person can be catheterized or if fit he/she can make urine directly in measuring utensil.
There are many things that affect an animal's urine output such as food intake. Beverage intake also affects an animal's urine output.
Measuring the ratio of urine calcium to urine creatinine corrects for differences in urine concentration due to variations in fluid intake and urinary output.
For a male OR female, drinking about 2 liters of fluid a day, the normal urine output should be 800 to 2,000 milliliters a day. Urine output below 500 milliliters a day is considered a low urine output and is a sign of disease.
Certainly. Decrease cardiac output would mean a decreased in blood flow to the kidneys, which would lead to reduced filtration, therefore urine output.
Decreased urine output is also known as Oliguria. Renal malfunctions or dehydration can cause Oliguria. The ICD-9 code for decreased urine output/oliguria is 788.5.
There are various factors which might decrease urine output. For example, if a person is dehydrated then they will urinate less.
You should be aiming for a urine output above 1 ml/kg/hr

Volume and Time
Usually when there is less than normal urine output it is associated with dehydration so the way it is described in a chart is "diminished urine output noted".
