Abstract
A warning device for indicating a reduction of breathing gas supply pressure in an air breathing conduit includes a warning device member disposed in the breathing conduit which has a connection to the gas supply and is movable in response to a drop in the air supply pressure beyond the predetermined amount into at least a partially blocking position so as to increase the flow resistance through the breathing conduit so that the patient using the device is warned by the condition. The device includes a correction element connected to the conduit which moves the warning member in a direction away from the blocking position so that the warning cycle is again initiated.
