CPAP, AutoCPAP, bi-level CPAP – devices for the treatment of sleep apnoea
CPAP devices are used to prevent apnoea while sleeping. In addition to standard devices (CPAP), therapy devices with automatic pressure adjustment (AutoCPAP) and those with different pressures for inhalation and exhalation (BiLevel) are produced as well.
There are two main challenges for CPAP devices: they have to operate very quietly on the one hand and supply enough air on the other hand. Since the device is used while sleeping, very strict requirements apply for noise emissions. Ideally the device operates so quietly that it is not perceived at all or that only a low hissing can be heard. The second focal point of guaranteeing adequate ventilation system performance is effected by the requirements for the fan controller. Responding very quickly to patient breathing is essential, especially during the transition from breathing in to breathing out or vice versa.
The Delphinus and Doroado devices developed by seleon set standards in terms of comfort and performance. Highly dynamic pressure control can be realised thanks to the patented algorithm to monitor breathing. This enables an extraordinarily fast reaction at the beginning of the inhalation phase and prevents the feeling of being short of air. In addition to quiet operation, the CPAP devices can guarantee that the required ventilation system performance is available for the user at all times.
