The present invention relates to a compressed air control device for a CPAP device and to a corresponding CPAP system. The compressed air control device comprises: a pressure measuring device (101) for measuring a variation of the pressure (P10) in a hollow body (10) of the CPAP device (1) and for generating a corresponding pressure signal (102); a pressure variation evaluating device (103, 104) for evaluating the measured variation of the pressure (P10) according to at least one predetermined criterion and for generating a pressure modulation control signal (106) based on the result of the evaluation; and a pressure modulating device (110) for receiving a substantially constant compressed air stream (DS) and for outputting a modulated compressed air stream (DSM) to the CPAP device (1), which is configured in such a way that, in response to the pressure modulation control signal (106), it modulates the pressure of the compressed air stream (DSM) output to the CPAP device (1). |
