What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This completed study tested whether an electronic system that listens to breathing sounds can improve safety during sedation for gastrointestinal endoscopy. 200 patients were randomly assigned to standard monitoring or the breath-sound system. The goal was to see if the device helps prevent low oxygen levels and other breathing problems. Results could lead to safer sedation practices.

What this could mean

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

Active substance
electronic respiratory sound monitoring system
What this could lead to
If effective, this system could help doctors avoid over-sedation and reduce breathing complications during routine endoscopy.
What could go wrong
This is a small, completed trial focused on monitoring, not a new treatment. The device may not significantly improve outcomes over standard care.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
