Summary

This study tests whether a high-flow nasal cannula (a device that delivers warm, moist oxygen) can prevent low oxygen levels during sedated gastrointestinal endoscopy in people at high risk for obstructive sleep apnea. About 600 adults with a STOP-Bang score of 5 or higher will be randomly assigned to receive either the high-flow nasal cannula or standard oxygen during their procedure. The goal is to see if this approach reduces the chance of hypoxia, a common complication during sedation.
