Abstract

An operating unit (2) sets ventilation parameters of a control unit (11) of a ventilator (1) that includes a gas dispensing device (10) for ventilation gases. The operating unit includes a display unit and an ventilation parameters input element (23, 24). Two or more of the parameters are linked via a relation condition stored in a relation storage module (40). A relation monitor (3) includes a deviation detector (31) detecting a transgression of the relation condition during parameter setting, and outputs warning information via a warning unit (32). This avoids a need for an operator to note the sometimes complicated connections and dependencies expressed in the relations during the parameter setting. The warning may be sent before the new setting value is sent from the operating unit to the control unit. Operating safety is increased and a risk of setting errors is minimized.
