Fluid therapy based on adjusted urine output rate, and associated systems, devices, and methods

A fluid therapy system, comprising:

• a urine measurement device configured to measure urine output of a patient;
• a diuretic source configured to provide a diuretic to the patient;
• a hydration fluid source configured to provide a hydration fluid to the patient;
• and
• a controller, wherein the controller is configured to—
• obtain, via the urine measurement device, a urine output rate of the patient;
• obtain a sodium excretion input for the patient;
• determine an adjusted urine output rate based on the sodium excretion input and the urine output rate;
• and
• based on the adjusted urine output rate, (i) cause the diuretic to be administered to the patient at one or more diuretic dosage rates and (ii) cause the hydration fluid to be administered to the patient at one or more hydration rates to produce a net fluid loss in the patient.
