Summary

This study tests whether adding a real-time carbon dioxide monitor (capnography) to standard vital sign checks can catch breathing problems earlier during painless gastrointestinal endoscopy. Researchers will enroll 460 patients and track how often oxygen levels drop below 95%. If it works, this simple device could make sedation safer, especially for older or higher-risk patients.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: microstream capnography nasal end-tidal carbon dioxide sampling tube
What this could lead to: If successful, this device could become a standard safety tool for sedation procedures, reducing breathing complications and making endoscopy safer for patients.
What could go wrong: This is a single-center study that hasn't started recruiting yet. The device adds monitoring but does not prevent all risks, and results may not apply to all hospitals or patient groups.
