Hidden danger after endoscopy? new study tracks oxygen drops
NCT ID NCT07445256
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study watches 100 adults after a sedated upper GI endoscopy to see how often their oxygen levels drop below normal. Researchers will track these episodes and any breathing problems that follow, without changing standard care. The goal is to better understand and improve recovery safety.
