Method for assessing a patient's fluid status and/or sensitivity to fluid removal, controller, and devices

摘要

The present invention relates to a method for assessing a patient's sensitivity to fluid removal from the patient's vascular system or to fluid replacement or addition with regard to the patient's hydration state, the method comprising the step of determining a value reflecting the distribution of fluid between at least two distribution spaces of the body of the patient or changes thereof from measured or calculated values, and assessing whether the value fulfills at least one criterion. It also relates to a controller, an apparatus, a device, a digital storage device, a computer program product, and a computer program.

主权项

1. A blood treatment system for treating the blood of a patient, comprising:
an obtaining system for obtaining a first value reflecting the distribution of fluid between at least a first and a second distribution space of the patient; and, a control system, wherein the control system determines whether said first value fulfils at least one criterion, the criterion being a saturation degree of at least one of the distribution spaces, the saturation degree being a ratio between the changes of the two distribution spaces over time, wherein the control system is configured to calculate a correlation between changes in patient weight over at least two measurements and values representing an anemia state of the patient or changes thereof at those measurements, wherein the control system is configured to compare the calculated correlation with a threshold or a range, wherein the threshold is the slope or inclination of a curve, and wherein the curve indicates the distribution of the fluid between at least the first and the second distribution space.
