Fluid therapy method

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.

Problems solved by technology

These patients often enter the emergency room with significant volumes of excess fluid and a number of complications due to this excess fluid.

There are a number of factors that contribute to the poor prognosis of these patients.

Patients with ADHF often have a number of co-morbidities, complicating their treatment and giving them a poor prognosis.

This also contributes to the fact that patient response to diuretics is unpredictable.

A paradox of the ADHF patient involves the fact that while these patients may have 40 additional liters of fluid in their body, they may be intravascularly dehydrated.

The injection of diuretics then only causes fluid to be lost from the already depleted intravasculature.

Once the patient fails to respond to diuretics, treatment becomes very difficult.

One of the ways ADHF kills patients is by retain
