Trial Title: Post-extubation Boussignac CPAP System in Adults With Moderate to Severe Obstructive Sleep Apnea

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

Eligibility Criteria:
Inclusion Criteria:~-\> 18 years of age~* ASA II-IV~* Previous diagnosis of moderate to severe obstructive sleep apnea~* diagnosed via polysomnography~* BMI \< 40~* scheduled for an abdominal or peripheral surgical procedure requiring endotracheal intubation and admission to hospital~Exclusion Criteria:~* BMI \> 40~* Age \<18 years~* inability to provide signed informed consent~* intra-thoracic~* head or neck surgery~* contraindication for immediate post-extubation application of CPAP~* not expected to be eligible for timely extubation following the surgical procedure

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Boussignac CPAP device (Type: EXPERIMENTAL): Patients previously diagnosed with obstructive sleep apnea and who are undergoing abdominal or peripheral surgery will have the Boussignac CPAP mask applied for 1 hour starting immediately post-extubation
- standard CPAP (Type: ACTIVE_COMPARATOR): Patients previously diagnosed with obstructive sleep apnea who are undergoing peripheral or abdominal surgical procedures will receive the standard-of-care for obstructive sleep apnea. This typically involves CPAP application only at night

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