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
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 Results may not be published yet.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 This study
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This status has not been confirmed recently, so it may be out of date.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 tests whether combining high-flow nasal oxygen with a vibrating membrane nebulizer helps patients with asthma or COPD flare-ups reach their target oxygen levels better than standard care with a nebulizer mask. Emergency medical services will compare a group receiving usual care to a group using the new device combination. The goal is to see which method achieves the desired oxygen saturation within 15 minutes, with different targets for asthma and COPD.

What this could mean

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

Active substance
Vibrating membrane nebulizer combined with high-flow nasal oxygen
What this could lead to
If this approach works, it could improve oxygen delivery during asthma and COPD flare-ups, helping patients reach target oxygen levels faster and more reliably in emergency settings.
What could go wrong
This is a small before/after study, not a randomized trial, so results may be influenced by other factors. The devices may be harder to use in the field, and some patients with severe breathing failure are excluded.
