This prospective observational study aims to evaluate the association between postoperative oxygenation, assessed by the SpOâ‚‚/FiOâ‚‚ ratio, and body mass index (BMI), STOP-BANG score, and postoperative analgesic methods in patients undergoing elective laparoscopic cholecystectomy in the reverse Trendelenburg position. Postoperative SpOâ‚‚ and FiOâ‚‚ values will be recorded within the first postoperative hour, and the SpOâ‚‚/FiOâ‚‚ ratio will be calculated. Analgesic techniques applied as part of routine clinical practice will be documented. The study does not involve any additional intervention beyond standard care. The findings are expected to contribute to a better understanding of factors associated with early postoperative oxygenation and hypoxemia risk.
