Abstract

A system is provided for controlling and monitoring therapy modules of a medical workstation. The system includes a first control and display unit, at least another control and display unit and at least one therapy module, which is either a ventilation module or an infusion module. The control and display units and the therapy module or therapy modules are connected to one another via bidirectional communications connections. The control and display units have a settable first display area for alarm and status reports of the therapy module or therapy modules and a second area for the display and modification of therapy settings of the therapy module or therapy modules. The communication between the control and display units is such that the display of the alarm and status reports for the therapy module or therapy modules can be turned off on one of the control and display units only if the display of the alarm and status reports of the therapy module or therapy modules is turned on, on at least one of the other control and display units and/or the communication between the control and display units is such that the display and modification of therapy settings of the therapy module or therapy modules can be turned off only if the display and modification is turned on, on at least one of the other said control and display units.
