First seen Jan 10, 2026 · Last updated Apr 29, 2026 · Updated 14 times
Summary
This study tests whether a high-flow nasal cannula (a device that delivers warm, moist oxygen at high speeds) can reduce the risk of dangerously low oxygen levels during sedated gastrointestinal endoscopy in critically ill patients. Researchers will enroll 450 adults with serious health conditions like liver cirrhosis or colon polyps who are scheduled for a scope procedure. Participants will receive either the high-flow oxygen or standard nasal oxygen, and the team will compare how often low oxygen events occur.
