Abstract: The present invention relates to a method for controlling a filtration rate during treatment of a body fluid, e.g., during hemofiltration or dialysis, comprising the steps of defining a target relation, or a development during dialysis thereof, between one or more calculated or measured value(s) reflecting the mass, concentration, or the volume of a substance comprised by a patient's tissue or bodily fluid, and one or more calculated or measured value(s) reflecting a patient's distribution space or an approximation thereof; during dialysis repeatedly calculating or measuring value(s) reflecting the mass, concentration or the volume of the substance and/or reflecting the distribution space or an approximation thereof, and determining the relation therebetween at least once; and controlling the filtration rate of the body fluid treatment device such that the determined relation is or approaches the target relation.

Abstract: Electrodes for a bio-impedance measuring device or a body composition monitor, the electrodes being integral with or being attached to a surface of at least one device belonging to a group of electronic and/or non-electronic devices used in the preparation of a dialysis treatment or during dialysis, in particular during peritoneal dialysis, the group preferably consisting of organizers of a continuous ambulatory peritoneal dialysis system (CAPD), automated peritoneal dialysis devices, automated peritoneal dialysis-cyclers (APD-Cycler), bioelectrical impedance analyzers (BIA), body composition monitors (BCM), hand-held electrodes holders for the electrodes, and dialysis apparatuses. Devices and methods used during dialysis are also described.

Abstract: 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 fulfils 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.

Abstract: A method and an arrangement for determining an overhydration parameter or a body composition parameter are disclosed. The method comprises: obtaining first bioimpedance measurement data of a patient from a first type of hioimpedance measurement (204), deriving bioimpedance calibration data from the first bioimpedance measurement data for calibrating second hioimpedance measurement data from a second type of bioimpedance measurement (205), obtaining the second bioimpedance measurement data from a second bioimpedance measurement of the patient (206), and calibrating the second bioimpedance measurement data using the calibration data to determine the overhydration parameter or the body composition parameter of the patient (207).

Abstract: The present invention relates to a method for calculating or approximating a value representing the relative blood volume (RBV) at a certain point of time, or a value representing the refilling volume of a patient that may be observed or found during or due to a blood treatment of the patient, the method involving considering one or more calculated or measured value(s) reflecting an overhydration level of the patient or an approximation thereof. It relates further to an apparatus and a device for carrying out the present invention, a blood treatment device, digital storage means, a computer program product, and a computer program.

Abstract: The invention relates to the field of monitoring the hydration- and/or nutrition status of a patient by means of bioimpedance measurement values. This is based on the problem of also being able to determine by such measurements the body composition of an amputated person simply and individually. The invention is based on the observation that volume compartments can also be determined in amputated patients by means of bioimpedance measurements when reference is made to the body models, used and established hitherto for patients without amputations, without major adaptation. Merely the determining of a characteristic factor for the amputation is necessary, which can be determined by comparative measurements in advance. In particular exceptional situations of multiple amputations, it can be indicated to submit additional parameters to increase accuracy. Then the body models hitherto can also be further used for these cases.

Abstract: A method for calculating or estimating or approximating one or more values representing parameters of a patient includes the step of interpolating or extrapolating of at least one later value of a first parameter taking into account at least one earlier value of the first parameter, at least one earlier and at least one later value of a second parameter, and a mathematical relation between the first and the second parameter. An apparatus, a blood treatment device, a digital storage device, a computer program product, and a computer program are also described.

Abstract: The subject matter is a patient supporting device for supporting a patient during a medical treatment, in particular a dialysis treatment, and a treatment apparatus with such a patient supporting device, and a corresponding method for controlling and/or regulating a medical treatment device, in particular a dialysis device, using such a patient supporting device.

Abstract: The present invention relates to a method for predicting the concentration or the mass of hemoglobin or an approximation thereof, respectively, in a body fluid and/or an extracorporeal sample thereof of a patient at a later, second point of time, the patient having theoretically or in reality been administered a certain dose of an erythropoiesis stimulating agent at an earlier, first point of time.
