Device for supplying a respiratory gas

摘要

The invention relates to an apparatus for supplying a respiratory gas to a patient within the context of diagnosis and/or therapy of sleep-related breathing disorders. In particular the invention concerns a CPAP unit with self-adaptive dual level pressure regulation. According to the invention there is provided an apparatus for supplying a respiratory gas comprising an electronic signal processing device for generating a pressure control signal (p) on the basis of signals (5) indicative in respect of the breathing activity and/or the physiological state of a person, wherein the signal processing device (1) has a signal input device and an extraction device (2) for generating data field entries (3) according to predetermined signal analysis procedures, and there is provided a pressure signal generator (4) for generating the pressure control signal (p), wherein the pressure signal generator (4) generates the pressure signal (p) taking into account at least selected data field entries (3) which are determined on the part of the extraction device (2).
