Can a nasal oxygen device prevent low oxygen during endoscopy in sleep apnea patients?
NCT ID NCT07155330
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a high-flow nasal cannula (HFNC) can reduce the risk of low oxygen levels during sedated gastrointestinal endoscopy in 80 adults with high-risk obstructive sleep apnea. Participants had a STOP-Bang score of 5 or higher and were undergoing gastroscopy, colonoscopy, or both. The goal was to see if HFNC prevents hypoxia, a common complication during sedation.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
high-flow nasal cannula (device)
What this could lead to
If it works, this could provide a simple way to prevent dangerous drops in oxygen during routine endoscopy for people with severe sleep apnea.
What could go wrong
This is a small, completed study with only 80 participants, so results may not apply to everyone. The device may not reduce hypoxia risk as hoped.
