Summary

Hypoxaemia 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.
