Patient hydration system with hydration state detection
View Patent ↗A patient hydration system with a patient urine output measurement device, a hydration fluid administration subsystem, and a controller, responsive to the patient urine output measurement device. The controller is configured to control the hydration fluid administration subsystem to administer hydration fluid to the patient to prevent dehydration of the patient. A hydration sensor is also included to detect at least one patient parameter indicative of the patient's hydration state.
1. A method of addressing contrast induced nephropathy, the method comprising:
injecting a contrast agent into a patient;
imaging the patient; and
inducing diuresis to drive any contrast agent through the patient's kidneys to reduce its toxic effects on the kidneys and prevent damage to the kidneys by:
setting a desired fluid balance,
collecting urine expelled by the patient in a urine collection bag,
weighing the urine collection bag,
employing a pump to infuse the patient with fluid from a fluid source,
weighing the fluid source,
automatically adjusting the pump based on the weight of the urine collection bag and the weight of the fluid source and controlling the amount of fluid infused into the patient based on the amount of urine expelled by the patient and the set desired fluid balance,
determining if a bolus amount of fluid is required for the patient in addition to the fluid infused to achieve the desired fluid balance and if so setting a desired bolus amount, and
if a bolus amount was set, automatically controlling the pump to infuse the set bolus amount into the patient.
2. The method of claim 1 further including the step of administering a diuretic to the patient.
3. The method of claim 1 in which collecting urine expelled by the patient includes catheterizing the patient.
4. The method of claim 1 in which catheterizing the patient includes inserting a urinary catheter in the urinary tract of the patient.
5. The method of claim 1 in which weighing the urine collection bag includes providing an indication when a urine collection bag has reached its capacity.
6. The method of claim 1 in which weighing the fluid source includes providing an indication when the fluid source is low on fluid.
