NCT04123821

Brief Summary

The goal of this prospective, multi-center, single-blinded randomized controlled trial is to assess the efficacy of NPA in reducing respiratory events in patients being admitted for GI endoscopy (colonoscopy, gastroscopy, endoscopic ultrasound) under deep sedation. The main question it aims to answer are: • \[Is the NPA used on patients undergoing gastrointestinal endoscopy efficient in reducing respiratory events?\] Participants will be randomly allocated into one of the two groups: NPA with 5L/min oxygen through nasal cannula (group A) or 5 L/min oxygen through nasal cannula alone (group B). Researchers will compare NPA group to nasal cannula group to see if the routine placement of an NPA can reduce the frequency of airway obstruction, hypoxemic events and airway maneuvers (chin lift, oral airway insertion, and mask-bag ventilation) during endoscopic sedation.
