Abstract

The device for controlling the overpressure generating turbine (3) comprises means (15, 17, 18, 20, 22) for detecting periodic variations in the regime of the turbine and means (I, E) for fixing two reference levels of the pressure delivered in order to modulate the overpressure provided by the turbine as a function of the respiratory parameters of the user which are detected in situ by a pressure sensor (8). Application in particular to respiratory aid for individuals suffering from respiratory disorders when sleeping. <IMAGE>
