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 Results may not be published yet.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 tests whether a speaking valve combined with a pressure measurement can predict if the upper airway is open in people with a long-term tracheostomy. 300 participants will wear the valve for 30 minutes while pressure is measured, then undergo a bronchoscopy for comparison. If accurate, this non-invasive method could replace the more invasive scope procedure.

What this could mean

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

What this could lead to
If successful, this could provide a non-invasive, simpler way to check if the upper airway is open in tracheostomy patients, reducing the need for bronchoscopy.
What could go wrong
This is an early diagnostic study, not a treatment. The test may not be accurate enough to replace bronchoscopy, and results may vary across patients.
