1. A fluid management system, comprising:
a measurement system configured to measure urine output from a patient;
a pump configured to provide hydration fluid to the patient; and
a control system operatively coupled to the measurement system and the pump, the control system being configured to—
obtain a urine output rate based on the measured urine output from the measurement system;
receive a desired net fluid loss rate for the patient;
during a first period, cause the hydration fluid to be provided, via the pump, to the patient at a hydration fluid rate; and
during a second period after the first period, and based on at least one of the urine output rate or the desired net fluid loss rate, adjust operation of the pump to increase the hydration fluid rate.
