Brief Summary
The purpose of this study is to evaluate the pre and postoperative CPAP compliance rate in OSA surgical patients with or without a CPAP prescription. In this study, all diagnosed OSA patients with or without a CPAP prescription will be approached for informed consent to enroll in the study. Documented OSA is defined as an OSA diagnosis based on a previous laboratory or portable PSG, or on the prescription of CPAP for OSA. The patients with a CPAP prescription will be followed up to determine their compliance with CPAP and data will be collected to determine the O2 saturation. Those patients with diagnosed obstructive sleep apnea without a CPAP prescription will also be followed to objectively determine the severity of OSA which would indicate whether they do not require CPAP owing to their mild OSA or they in fact may require CPAP due to change in weight etc. Preoperative overnight oximetry will be performed on all the OSA patients at home before surgery. In the postoperative period, all patients will be followed up with a nocturnal oximetry in the first two post-operative nights of hospital stay. Postoperative compliance to CPAP will be evaluated and recorded in all the patients. The patients' charts will be reviewed for any postoperative complications. The clinical management of patient will be left to the discretion of the perioperative care team.

Outcome Measures
Primary Outcomes (1)
CPAP compliance
CPAP compliance (average CPAP use ≥ 4hrs / night)
(average CPAP use ≥ 4hrs / night).
Study Arms (2)
CPAP prescription group
Patients with a CPAP prescription (both compliant and noncompliant)
Without a CPAP prescription
Patients without a CPAP prescription to satisfy our primary goals/objectives.
Eligibility Criteria
All adult surgical patients (\>18 yr) with a diagnosis of OSA with or without a CPAP prescription. Scheduled for a non-cardiac surgery (general surgery, orthopedics, urology, plastic surgery and spine) that is expected to require a postoperative hospital stay of more than one night.
You may qualify if:
- All adult surgical patients (\>18 yr) with a diagnosis of OSA with or without a CPAP prescription.
- Scheduled for a non-cardiac surgery (general surgery, orthopedics, urology, plastic surgery and spine) that is expected to require a postoperative hospital stay of more than one night.
You may not qualify if:
- They are unwilling or unable to give informed consent to the study.
- They are on supplemental oxygen preoperatively (daytime or nocturnal).
- They are pregnant.
- Surgery included tonsillectomy, septoplasty, uvuloplasty, pharyngoplasty, tracheostomy, or prolonged (\> 48 hrs) postoperative mechanical ventilation of the lungs is anticipated. These procedures/interventions are likely to cure or at least modify the severity of OSA.
