New oxygen method may protect sleep apnea patients during routine scopes

This study looked at whether a high-flow nasal cannula (a device that delivers warm, humidified oxygen) can reduce the risk of dangerously low oxygen levels during sedated gastrointestinal endoscopy in people at high risk for obstructive sleep apnea. Researchers enrolled 80 adults with a STOP-Bang score of 5 or higher who were scheduled for procedures like gastroscopy or colonoscopy. The goal was to see if this oxygen method helps prevent hypoxia, a common complication during sedation.
