Abstract
A fluid replacement method including: determining the amount of urine expelled by a patient; infusing via a pump fluid from a first fluid source into a patient; determining an amount of fluid infused into the patient from the first fluid source; adjusting the operating of the pump based on the determined amount of urine expelled and the amount of fluid infused into the patient; setting a desired fluid balance for the patient; setting an amount of at least one additional fluid delivered to the patient, wherein the at least one additional fluid is not pumped into the patient; calculating an actual fluid balance based on the determined urine output, the determined amount of fluid infused into the patient from the first fluid source, and the set amount of said at least one additional fluid delivered to the patient; and automatically controlling the pump based on the actual fluid balance and the set desired fluid balance so the actual fluid balance conforms to the desired fluid balance.
