Most OSA patients were not obese and/or admitted over night so the study was not feasible.

The purpose of this study is to assess the efficacy of the Boussignac positive airway pressure system (a mask) applied immediately following post-operative extubation in improving lung function in patients with obstructive sleep apnea (OSA). Assessments will be done before surgery and then at 1, 2 and 24 hours following extubation and will be compared to standard care for perioperative airway support. The study aims to give a broader and more inclusive picture (than the current literature) in terms of whether the Boussignac CPAP system should be considered for utilization by anesthesiologists caring for surgical patients with OSA.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Boussignac CPAP device | 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 | 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 |

| Boussignac CPAP device | Device | Is a continuous positive airway pressure (CPAP) system marketed in Canada and the US for the treatment of Obstructive Sleep Apnea. The main difference is that this system is portable wheres the standard hospital CPAP is not. This allows for the application immediately post-extubation. |
| Measure | Description | Time Frame |
|---|---|---|
| percent forced vital capacity %(FVC) | %FVC will be assessed 24 hours postoperatively in patients who received the Boussignac CPAP mask immediately post-extubation and these values compared to those of patients who received the standard-of-care treatment for obstructive sleep apnea | 24 hours postoperatively |
| Measure | Description | Time Frame |
|---|---|---|
| % forced expiratory volume in 1 second (FEV1) | 1,2 and 24 hours post-operatively |
| Measure | Description | Time Frame |
|---|---|---|
| Peak expiratory flow rate (PEFV) | 1,2 and 24 hours postoperatively |
