Participants: Following full-night polysomnography (PSG) to confirm the presence of sleep-disordered breathing, patients were randomized to three additional full-night-attended PSGs with continuous positive airway pressure (CPAP), ASV, and servo-ventilation with an initial mandatory pressure support of 6 cm water (H2O) ASV manual Minimum Pressure Support (PSmin). Following the PSGs, patients were sent home with EncoreAnywhere and ASV with or without mandatory pressure support.
