What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

Summary

This study compares two ways of giving oxygen during sedation for medical procedures done outside the operating room: high-flow nasal oxygen and a standard face mask. Researchers measure brain oxygen levels continuously to see which method keeps the brain better oxygenated. One hundred adults scheduled for elective procedures will take part, with half receiving each oxygen method.

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 high-flow nasal oxygen proves better at maintaining brain oxygen levels, it could become the standard way to deliver oxygen during sedation, reducing the risk of low oxygen in the brain.
What could go wrong
This is a small, early-stage study focused on measuring oxygen levels, not on hard clinical outcomes like preventing complications. The results may not change practice without larger trials.

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 100 people

The number the study aims to enrol. It can still change while the study runs.
