A trigger device for controlling the operation of a control valve for an artificial respiration system includes a pressure sensitive control element which is admitted with the pressure of a line carrying the respiration gas and it operates and causes a deflection of an actual value indicator which moves in its deflection range past as adjustable inductive barrier. The inductive barrier is connected to an electronic control unit so that deflection of the actual value indicator interrupts, in dependence upon its setting in respect to the inductive barrier, the recoupling of the electronic control unit in order to vary an electrical impulse which is amplified for controlling the operation of a pressure valve in the respiratory gas supply system.
