Outcome Measures

Primary Outcomes (1)

  • Apnea Hypopnea Index (AHI)

    Subjects completed 2 overnight sleep studies (polysomnography (PSG)). The Apnea Hypopnea Index (AHI) metric is collected from the PSG study. Patients were equally distributed according to the therapy used first (ASV then Bi-Level or Bi-Level then ASV).

    Up to 1 month

Secondary Outcomes (1)

  • Patient Comfort

    Up to 1 month

Study Arms (2)

Adaptive Servo-Ventilation (ASV) then BiLevel PAP

EXPERIMENTAL

Adaptive servo-ventilation (ASV) is a form of positive airway pressure (PAP) that is delivered based on the needs of the individual. ASV adjusts to the breathing events the individual is experiencing and provides enough PAP to resolve the breathing event. This is a crossover study, so all patients enter both treatment groups.

Device: Adaptive servo-ventilation (ASV)Device: Bi-Level PAP

Bi-Level PAP then Adaptive Servo-Ventilation (ASV)

EXPERIMENTAL

Bi-level pressure delivers two pressures, IPAP and EPAP. Both pressures are fixed and do not adjust based on the individuals breathing events. This is a crossover study, so all patients enter both treatment groups.
