Summary
This prospective observational study evaluates whether the preoperative ROX index can predict early postoperative hypoxemia in patients undergoing bariatric surgery. Preoperative ROX measurements, along with ARISCAT and STOP-Bang scores, will be assessed for their association with hypoxemia occurring within the first 12 postoperative hours.
