Abstract

A console includes a weighing subsystem responsive to a first fluid source and a urine collection chamber. A pump infuses fluid from the first fluid source into a patient. A processing subsystem is responsive to the weighing subsystem. Based on the weight of the first fluid source and of the urine collection chamber, urine output and amount of fluid infused into the patient from the first fluid source are determined. A user can set a desired fluid balance and the amount of at least one additional fluid delivered. An actual fluid balance is calculated based on the determined urine output, the determined amount of fluid infused from the first fluid source, and the set amount of the additional fluid delivered. The pump is controlled based on actual fluid balance and set desired fluid balance so actual fluid balance becomes the same or approximately the same as the desired fluid balance.
