A method for providing feedback on an expected and/or required user interaction in a blood purification device is disclosed. The method includes monitoring, at a current position in an operational flow of the blood purification device, whether a user interaction is expected and/or required in a subsequent step in the operational flow. If it is determined in the monitoring step that a user interaction is required and/or expected, the kind of required and/or expected user interaction is determined. A user interaction feedback indicating the determined kind of user interaction required and/or expected in the at least one subsequent step is then proactively activated at an active element corresponding to the user interaction in a graphical user interface.
