Zusammenfassung:	A device including a chamber having two inlets and an outlet. One inlet is connected to an expiratory valve in a lung ventilator or like machine, the other inlet is in communication with a whistle and the outlet is connected to an aspirator. The device gives an intermittent audible signal when the ventilator is operating and saves the operator of the ventilator from having to look at the expiratory valve thereof to verify its correct operation.
