Obtaining control settings for a dialysis machine

A logic device for generating control settings to a dialysis machine which is configured to perform treatment sessions of renal replacement therapy, said logic device being adapted to generate, prior to each treatment session for an individual patient, a set of current control settings of machine-related parameters to be applied in the treatment session, said logic device comprising:

• means for obtaining a set of therapeutic targets comprising a target value of one or more physiological parameters for the patient, wherein the target value represents part of a desired status of the patient after the treatment session;
• means for obtaining status data that represents a current status of the patient prior to the treatment session;
• and
• means for computing, as a function of the set of therapeutic targets and the status data, the set of current control settings of the machine parameters, wherein the means for computing is configured to compute at least part of the current control settings based on a predictive model that estimates the physiological response of the patient to the machine-related parameters during the treatment session, such that the set of current control settings of the machine-related parameters enable the dialysis machine to achieve said target value of one or more physiological parameters for the patient at the end of the treatment session.
