Restrictive versus liberal rate of extracorporeal volume removal evaluation in acute kidney injury

A method of controlling a continuous dialysis machine comprising:

• determining a net fluid removal rate in volume/mass/time, comprising:
• calculating a predicted body weight of the patient based on patient's height;
• determining a net fluid removal rate from the patient in volume/mass/time based on the predicted body weight of the patient and selection of a restrictive strategy or a liberal strategy;
• calculating a total rate of intravenous fluids infused into the patient in volume/mass/time;
• and
• adding the total rate of intravenous fluids infused to the net fluid removal rate;
• and
• setting the continuous dialysis machine at the final net fluid removal rate to remove fluid from the patient.

A continuous dialysis system comprising:

• an electronic tool structured and configured to determine a net fluid removal rate component in volume/mass/time, comprising:
• receiving first information indicative of predicted body weight of a patient;
• receiving second information indicative of a total rate of continuous intravenous fluids infused into the patient in volume/mass/time;
• and
• determining a net fluid removal rate from the patient in volume/mass/time based on the predicted body weight of the patient and selection of a liberal strategy or a restrictive strategy;
• and
• adjusting the net fluid removal rate based on the total rate of continuous intravenous fluids infused;
• and
• an algorithm, in communication with the electronic tool, is structured and configured to provide output comprising the patient's net fluid removal rate to be set on the CKRT machine based on the predicted body weight, the total rate of continuous intravenous fluids infused into the patient, and the selection of the restrictive strategy or the liberal strategy.
