ABSTRACT:
A respirator is provided with a gas-metering device for respiration gases, a control unit influencing and monitoring the metering of the gas, an input unit connected to the control unit for introducing commands into the control unit, a display unit outputting parameters, a rotary knob changing preselected parameters, and with an acknowledge switch, which takes over the changed parameter as a new set value into the control unit and is actuated by the rotary knob. The display unit is designed as an interactive flat screen with a contact-sensitive surface. Data entry sectors with setting segments and output sectors for parameters to be displayed are provided within the flat screen. The input unit is designed as a keypad arranged on the side of the flat screen. At least preselected data entry sectors on the flat screen can be switched by means of the keypad. The rotary knob and/or the acknowledge switch are/is switched into functional connection with the selected setting segment by touching at least one of the setting segments within a data entry sector.
