CPAP devices are used to prevent apnea during sleep. In addition to standard devices (CPAP), devices with automated therapy pressure tracking (AutoCPAP) and devices with different pressures for inhalation and exhalation (BiLevel) are also manufactured.


There are two main requirements for CPAP devices: On the one hand, they must operate very quietly, and on the other hand, they must supply enough air. Since the device is used during sleep, very high demands must be placed on noise emission. Ideally, the device should operate so quietly that it is not noticed or at least only a low level of noise can be heard. The second focus, to ensure sufficient air performance, results in the requirements for the fan control. It is necessary to react very quickly to the patient’s breathing, especially during the transition from inhalation to exhalation or vice versa.


The Delphinus and Doroado devices developed by seleon set standards in terms of comfort and performance. Due to the patented algorithm for breath monitoring, a very dynamically working pressure control can be realized. This enables an extraordinarily fast response at the beginning of the inhalation phase and prevents the feeling of air limitation.

In addition to quiet operation, the CPAP devices can ensure that the necessary air output is available to the user at all times.
