Participant Flow

Participants were recruited from pain treatment centers and clinics by either Pain Center/Clinic staff or staff from a Sleep Testing facility.

74 participants were screened; 40 were excluded after completing the diagnostic PSG (did not meet the inclusion/exclusion criteria).

Measure
Diagnostic Polysomnography (PSG)
A Diagnostic PSG was performed using the core equipment available to determine eligibility into the overnight portion of the study.
Continuous Positive Airway Pressure (CPAP)
Airway pressure delivered at a constant pressure level. CPAP: continuous positive airway pressure servo ventilation manual: servo ventilation titrated in manual mode
Servo Ventilation Auto Mode (autoSV)
Inspiratory and expiratory pressures automatically determined by the servo ventilation device. servo ventilation auto: Expiratory pressure automatically adjusted to stabilize the upper airway. Inspiratory pressure automatically adjusted to deliver consistent peak flow. CPAP: continuous positive airway pressure servo ventilation manual: servo ventilation titrated in manual mode
Servo Ventilation Manual (Manual SV)
Inspiratory and expiratory pressures automatically determined by the servo ventilation device with mandatory minimal inspiratory minus expiratory pressure difference. servo ventilation manual: servo ventilation titrated in manual mode
