A medical apparatus, such as a dialysis machine (e.g. a hemodialysis machine or a peritoneal dialysis machine), includes a plurality of components, one or more sensors corresponding to the components and configured to detect signals, a display and a control unit. The control unit is configured to: receive signals from the one or more sensors, determine, from the signals, a status of the medical apparatus, and determine control commands for the display based on the determined status for status-dependent control of the display. The described apparatus improves the human-machine interface in terms of set-up time, operating time and freedom from errors. Depending upon the determined status, different status-specific menus may be illustrated on the display in order to assist the user when operating the apparatus or advise the user about any errors or subsequent steps.
