during sedated gastrointestinal endoscopy exceeds 40 % in morbidly obese (BMI ≥ 35 kg m-²) patients. High-flow nasal cannula alone often fails because of persistent airway collapse. A recent innovation in this domain is the COMBO Endoscopy Oropharyngeal Airway-a multifaceted device that encompasses capnography monitoring, bite block , oxygenation support, and oropharyngeal airway management.The purpose of this study is to investigate whether the combination of the COMBO Endoscopy Oropharyngeal Airway and High-Flow Nasal Cannula oxygenation reduces the incidence of hypoxemia in this population.",[131,132,133,134],"Hypoxemia","Esophageal Cancer","Morbidly Obese Patients","Gastric Cancer",[136,131,137,138,139],"COMBO Endoscopy Oropharyngeal Airway","Sedation","Gastrointestinal Endoscopy","high-flow nasal cannula","2026-03-09",{"date":142,"type":143},"2026-03-11","ACTUAL",{"date":145,"type":143},"2025-10-24",{"date":147,"type":125},"2027-08-20",{"name":5,"class":6},5]
