Brief Summary
The best perioperative strategy for obstructive sleep apnea (OSA) in bariatric surgery remains unclear. A strategy is to monitor patients and administer preventive oxygen therapy during the first postoperative night. However it is unknown what if preventive oxygen therapy is necessary. The goal of this trial is to compare the Apnea-Hypopnea Index (AHI) in participants with or without preventive oxygen therapy. Methods: Participants are patients who underwent bariatric surgery without treated OSA and will be will be randomized into arm A or arm B: Arm A: First postoperative night in the hospital with preventive oxygen therapy (standard care), Arm B: First postoperative night in hospital without preventive oxygen therapy (intervention).

Outcome Measures
Primary Outcomes (1)
Apnea-Hypopnea Index (AHI)
AHI will be measured by a home sleep study device (Watchpat300) and will be compared between both arms, the higher the AHI the more severe the sleep apnea
First postoperative night
Secondary Outcomes (24)
Complication rate
Until 30 days after surgery
The number of nursing interventions
First postoperative night
Type of nursing interventions
First postoperative night
Oxygen Desaturation Index (ODI)
First postoperative night
AHI during Rapid Eye Movement (REM) sleep

ACTIVE COMPARATORInterventions
Participants will not receive preventive oxygen 2L during the first postoperative night after bariatric surgery.
Participants will receive preventive oxygen 2L during the first postoperative night after bariatric surgery, standard care.
