Abstract

The invention relates to a device for supplying a respiratory gas to a patient within the scope of the diagnosis and/or the treatment of sleep-related breathing disorders. The invention especially relates to a CPAP appliance comprising self-optimising dual level pressure regulation. According to the invention, the device for supplying a respiratory gas comprises an electronic signal processing device for generating a pressure control signal (p) on the basis of indicative signals (5) relating to the breathing activity and/or the physiological state of a person. The signal processing device (1) comprises a signal inputting device and an extraction device (2) for generating data field entries (3) according to predefined signal analysis procedures. A pressure signal generator (4) is provided for generating the pressure control signal (p), taking into account determined data field entries (3) which are at least selected by the extraction device (2).
