Fluid therapy method
First Claim
1. A fluid therapy method comprising:
- setting a urine output rate desired threshold by inputting the urine output rate desired threshold into an input section of a console;
setting one or more desired negative net gain rates by inputting one or more desired negative net gain rates into the input section of the console;
monitoring the urine output of a patient using a microcontroller;
the microcontroller automatically administering a fluid to the patient at increasing rates to equal to or approximately match the patient'"'"'s increasing urine output rates until urine output rate reaches the set urine output rate desired threshold;
upon the urine output rate reaching the set urine output rate desired threshold the microcontroller automatically thereafter administering the fluid to the patient at rates to achieve the set desired negative net gain rate.

Abstract
A fluid therapy method for an ADHF patient includes setting a urine output rate desired threshold, setting one or more desired negative net gain rates, and optionally setting a total fluid loss goal. The urine output of the patient is monitored and fluid is automatically administered to the patient at increasing rates to equal to or approximately match the patient'"'"'s increasing urine output rates until the patient'"'"'s urine output rate reaches the set urine output rate desired threshold. Thereafter, fluid is administered to the patient at rates to achieve the set desired negative net gain rate until the fluid loss goal is reached. Thereafter, until the end of therapy, fluid is administered to the patient at rates equal to or approximately equal to the monitored urine output rates.

21. A method of treating a patient having excess fluid, the method comprising:
-
inputting a urine output rate desired threshold into an input section of a console, the console including a microcontroller and a memory to store values and information; inputting a negative net fluid gain rate into the input section of the console; inputting a desired total fluid loss goal into the input section of the console; administering a diuretic to the patient to induce urine output; for a first therapy period after beginning the diuretic administration, the microcontroller driving the urine output rate of the patient to a higher level matching or exceeding the set urine output rate desired threshold by automatically controlling a pump in the console to infuse fluid into the patient at rates which match or closely match the patient'"'"'s urine output rates resulting in little or no total fluid loss; and for a second therapy period after the set urine output rate desired threshold is reached, the microcontroller inducing fluid loss at said set negative net fluid gain rate by automatically controlling the pump to decrease the amount of fluid infused and infusing fluid at rates which are less than but a function of the patient'"'"'s urine output rates until said set desired total fluid loss goal is reached. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
