Comparison of Sleep Disordered Breathing Events Detected by the CPAP Device "prismaLine" With Polysomnography

The evaluation of residual sleep disordered breathing (SDB) in sleep apnea (SA) after initiation of continuous positive airway pressure (CPAP) therapy is important to verify the therapeutic success. In clinical practice, the internal records of CPAP devices are utilized to determine the therapeutic success, during either medical consultations or telemetric observation. This study was designed to evaluate the quality of SDB Event Indices (EI), which are recorded by the CPAP device (Prisma, Löwenstein Medical Technology). The detected events of a manual scored polysomnography (PSG) in the sleep laboratory will be compared with the simultaneously recorded events of the CPAP device. This shall lead to recommendations regarding the situations, and in which degree the event detection of the CPAP devices may be meaningful to determine the therapeutic success of home sleep apnea therapy.
