High-flow nasal oxygen vs mask for people with belly fat having sedated stomach scope
Part of Digestive system, Lungs & breathing clinical trials.
This study compares two ways of giving oxygen during a sedated gastroscopy for people with visceral obesity (extra belly fat). One method uses a high-flow nasal cannula, the other a face mask. The goal is to see which keeps oxygen levels more stable.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are scheduled for a sedated gastroscopy (a scope to look at your stomach while you are asleep).
- You have excess belly fat (visceral obesity) — your body mass index is 28 or higher and your BRI score is 5.46 or higher.
- You are generally healthy enough for light sedation (ASA class Ⅲ or less).
- You do not have serious heart or lung problems, a recent cold, nose conditions, or a bleeding disorder.
- You are not pregnant, and you have not had chest surgery in the last week.
- You are not allergic to the drugs used during the procedure.

This trial tests if using high-flow oxygen through the nose before surgery helps patients who need emergency surgery and have a full stomach. It may make oxygen levels safer during the start of anesthesia.
This trial tests whether giving extra oxygen through a nasal tube during a sedated GI scope (gastroscopy or colonoscopy) helps people with COPD breathe more easily. It may reduce the risk of low oxygen levels during the procedure.
This trial tests a special breathing tube to see if it can prevent low oxygen levels during sedated endoscopy in people with obesity. If you are scheduled for both an upper endoscopy and colonoscopy, this study may help make the procedure safer.
This study tests if high-flow nasal oxygen can prevent oxygen drops during sedated endoscopy in patients with severe obstructive sleep apnea. It may help people who are at higher risk of breathing problems during the procedure.
This study tests whether high-flow oxygen delivered through the nose helps children breathe better during a sedated procedure to look inside their lungs. Researchers want to see if this oxygen method prevents low blood oxygen levels during the procedure.
This trial tests whether a breathing tube placed in the nose (nasopharyngeal airway) combined with high-flow oxygen can improve safety during painless gastroscopy in people with obesity. It may help you breathe better while sedated.
