Trial Title: CPAP vs AutoCPAP for Treatment of Obstructive Sleep Apnea (OSA) in the Postoperative Setting

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: TRIPLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Known OSA patients well-controlled by CPAP (not hypoxemic i.e. Oxygen Saturation (SaO2) ≥ 89% and post-treatment Apnea Hypopnea (AHI) \<10) and compliant ( \> 3 hours per night) presenting for elective inpatient surgery to MetroHealth Medical Center~2. Elective extremity or lower abdominal surgery~3. Age \>18 years~Exclusion Criteria:~1. Surgery that may cause hypoxemia from causes other than the effect on upper airway patency e.g. any thoracic surgery, upper abdominal surgery, head and neck surgery.~2. Surgery on the upper-airway.~3. Any condition that may interfere with application of CPAP mask e.g. trauma, surgery on the face, vomiting, naso-gastric intubation etc.~4. OSA treated with a device other than CPAP e.g. Bilevel positive pressure or V-Positive Airway Pressure~5. OSA needing very high levels of CPAP i.e. \> 16 cms to achieve adequate control~6. OSA or other underlying cardiopulmonary conditions that require supplemental oxygen~7. Patients with decompensated congestive heart failure or advanced Chronic Obstructive Pulmonary Disease (COPD) (FEV1\<35% of predicted)~8. Patients with neuromuscular impairment~9. Patients with central sleep apnea~10. Pregnant patients~11. Decisional impaired subjects who are not able to consent

Study Arms:
- Autoadjusting CPAP (VPAP auto) (Type: EXPERIMENTAL): The intervention will be the use of an Autoadjusting CPAP unit that will be applied to the subject during the 8 hours overnight the first night after surgery (study night). During this time, they will undergo a full night attended polysomnogram in their hospital room.
- CPAP arm (usual care) (Type: ACTIVE_COMPARATOR): The intervention will be the use of the subject's own CPAP machine and this will be applied to the subject during the 8 hours overnight the first after surgery (study night). During the study night, they will undergo full polysomnography in their hospital room.

Based on this trial design, predict the completion outcome and termination type (if applicable).
