Abstract
Devices, systems, and methods for delivering fluid therapy to a patient are disclosed herein. An exemplary method can comprise obtaining a urine output rate from a patient; causing a diuretic to be provided to the patient at a dosage rate, wherein the dosage rate is increased over a period of time such that the urine output rate increases to be above a predetermined threshold within the period of time; and causing a hydration fluid to be provided to the patient at a hydration rate. The hydration rate can be set based on the urine output rate to drive net fluid loss from the patient.
Claims10
A fluid therapy system, comprising:
- a urine measurement device configured to measure urine output from a patient;
- a pump configured to provide a diuretic to the patient;
- 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 comprising—
- obtaining a urine output rate from the urine measurement device;
- causing the diuretic to be provided, via the pump, to the patient at an initial dosage rate;
- increasing the dosage rate of the diuretic from the initial dosage rate to one or more additional dosage rates higher than the initial dosage rate;
- after increasing the dosage rate, receiving an indication that (i) the urine output rate is above a predetermined threshold and/or (ii) a predetermined time period since causing the diuretic to be provided has elapsed;
- and
- after receiving the indication, reducing the dosage rate of the diuretic to a reduced dosage rate that considers multiplying a value of a total amount of the diuretic delivered by a nonzero percentage.

- a pump configured to provide a diuretic to the patient;
- one or more processors;

- after causing the diuretic to be provided, receiving an indication that (i) the urine output rate is above a predetermined threshold and/or (ii) a predetermined time period since causing the diuretic to be provided has elapsed;
- and
- after receiving the indication, reducing the dosage rate of the diuretic, wherein the reduced dosage rate is obtained via an algorithm utilizing a nonzero percentage of a total amount of the diuretic delivered.
