Observational Study of the Value of Using Obstructive Sleep Apnea-hypopnea Syndrome (CPAP) Ventilation on the Occurrence of Respiratory and Cardiovascular Complications in Patients at High Risk of Obstructive Apnea Syndrome During Postoperative Sleep Surgery of a Major Abdominal Surgery.

Study Overview
=================
Brief Summary
-----------------
The presence of an obstructive sleep apnea-hypopnea syndrome (OSAHS) is a perfectly identified cardiovascular and metabolic risk factor responsible for excess mortality in patients with severe OSAHS, while life expectancy, when the SAHOS is treated by continuous positive airway pressure (CPAP) is close to that of the general population. It also represents a factor of excess mortality, little known and poorly explored, in relation to morbidity and mortality occurring during the perioperative period accompanying any general anesthesia.
