1. A fluid therapy system comprising:
one or more processors; and
tangible, non-transitory computer-readable media having instructions that, when executed by the one or more processors, cause the fluid therapy system to perform operations to cause a net fluid loss from the patient, the operations comprising—
receiving a first indication that urine output of a patient is at or above a first urine output threshold and below a second urine output threshold;
based on and after receiving the first indication, causing hydration fluid to be infused to the patient at a first hydration fluid rate, such that a first difference exists between the first hydration fluid rate and the urine output of the patient when the first indication is received, wherein the first hydration fluid rate is less than a first predetermined rate while the urine output is below the second urine output threshold;
receiving a second indication that the urine output is at or above the second urine output threshold; and
based on and after receiving the second indication, causing the hydration fluid to be infused at a second hydration fluid rate at or above the first hydration fluid rate, such that a second difference exists between the second hydration fluid rate and the urine output rate when the second indication is received, wherein the second difference is greater than the first difference, and wherein the second hydration fluid rate is less than the urine output.
