The device settings applied in the treatment night are defined by the study protocol (see interventions). Following the auto-CPAP treatment night, study participation is completed. Any following treatment and patient care is administered according to clinical routine.\n\nPrimary and secondary outcome measures of sleep stage and respiratory event indices are evaluated at diagnostic night and auto-CPAP treatment night.\n\nThe enrollment consists of two phases. During phase 1 (training phase) 10 participants are enrolled and complete the study protocol. Phase 1 serves as a training phase to establish a common standard of data quality and acquisition. Data of the training phase are not included in the statistical analysis.
