Brief Summary
Continuous Positive Airway Pressure (CPAP) is the most effective treatment for the Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS). CPAP stabilizes the airway and prevents instability and collapse. With a stable and patent airway, breathing continues in a normal manner, gas exchange is improved, and there is no disruption of sleep related to disturbed breathing. Auto Servo Ventilation (Auto SV) is a mode of positive airway pressure used to treat obstructive and complex central sleep apnea. The main features of the Auto SV mode include:
- Normalization of ventilation by automatically adjusting Inspiratory Positive Airway Pressure (IPAP) pressure to achieve a target ventilation. IPAP is increased or decreased to help stabilize the ventilation.
- Provision of timed, back-up breaths during central apneas. The optimal back-up rate is automatically determined by the device based on the patient's breathing.
- Automatic control of Expiratory Positive Airway Pressure (EPAP) to treat obstructive events. Several manufacturers produce these types of devices. The algorithms used to determine the IPAP, EPAP and minimum respiratory rate are different. The largest number of these devices currently in use are the BiPAP AutoSV Advanced System One (Philips Respironics, Murrysville PA) and the Variable positive airway pressure (VPAP) Adapt (ResMed Corp., San Diego CA).

Outcome Measures
Primary Outcomes (1)
Average Apnea Hypopnea Index Among Different Polysomnography Devices.
The Apnea Hypopnea Index is the number of the apneas and hypopneas during one hour of sleep. The average of these events over one night were compared during each overnight device use.

Eligibility Criteria
You may qualify if:
- Ability to provide consent
- Age ≥ 21
- Currently prescribed servo ventilation therapy at home
- At least two weeks of recent adherence and efficacy data from PAP device demonstrating adequate use of therapy (at least 4 hours of use per night and use on at least 9 of 14 nights)
