In a method and system to determine and display assistive information related to the current operating status of a medical apparatus at a mobile auxiliary device, operating parameters describing the current operating status of the medical apparatus are transmitted to the mobile auxiliary device via a wireless (in particular bidirectional) communication connection, and are evaluated at the mobile auxiliary device via a mobile application in order to determine the assistive information, whereupon the assistive information is displayed at least in part by the mobile application.
