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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether giving high-flow nasal oxygen (HFNO) during upper GI endoscopy in high-risk patients (e.g., those with sleep apnea or obesity) reduces the risk of blood oxygen levels falling too low. 180 patients were randomly assigned to receive either HFNO or standard oxygen via face mask or nasal cannula. The goal was to see if HFNO could prevent the need for emergency airway maneuvers.

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 oxygen (HFNO) delivered via a device
What this could lead to
If it works, this could provide a safer way to give sedation during upper GI endoscopy in high-risk patients, reducing the need for emergency airway procedures.
What could go wrong
This is a small, completed study (180 patients) and results may not apply to all settings. The intervention may not significantly reduce oxygen drops or could cause discomfort.

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.
