What is too much urine to drain from a foley at one time?

Answer 1

This would depend on the medications and fluids the person is receiving. Generally, the minimum amount is 30cc per hour. There is not a maximum. The Foley catheter is in the bladder and drains the urine that is present in the bladder. The amount in the bladder depends on whether the person is receiving high volumes of IV fluids or medications to decrease the volume of fluid in the bloodstream. Both of these would increase the volume of urine.

An example of this would be a person in congestive heart failure. He/she would be given a drug called a diuretic which would increase the amount of urine produced to decrease the work for the heart. The diuretic increases urine production to decrease the excess fluid in the bloodstream. There are also medical conditions that cause excess urine production. It is most important to measure overall volume in compared to volume out.

Therefore, the answer regarding the volume of urine is really dependent on the other factors involved in the person's medical condition and their drugs.
