Study Overview
Brief Summary
Hypoxia represents the prevailing adverse occurrence during the sedation of patients undergoing Endoscopic Retrograde Cholangiopancreatography (ERCP) with propofol. 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. This device has been purposefully designed to cater to the unique requirements of endoscopic procedures. The principal objective of this study is to assess the efficacy of the COMBO Endoscopy Oropharyngeal Airway in reducing the incidence of hypoxia in patients undergoing ERCP under sedation.

Outcomes
Primary Outcomes
The incidence of hypoxia
Time Frame: Patients will be followed for the duration of hospital stay, an expected average about 2 hours
75% ≤ SpO2 \< 90% for \<60 s
Secondary Outcomes
- The incidence of sub-clinical respiratory depression(Patients will be followed for the duration of hospital stay, an expected average about 2 hours)
- The incidence of severe hypoxia(Patients will be followed for the duration of hospital stay, an expected average about 2 hours)
