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 Results may not be published yet.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

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

Summary

This study will test a handheld ultrasonic spirometer against a conventional hospital spirometer in 100 adults with chronic respiratory diseases like COPD or asthma. Each participant will use both devices to see if the portable one gives accurate and reliable results. If successful, it may offer a convenient way for patients to monitor their breathing at home.

What this could mean

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

Active substance
handheld ultrasonic spirometer
What this could lead to
If the handheld device proves accurate, it could allow patients to monitor lung function at home instead of only in a hospital.
What could go wrong
This is a small, early-stage comparison study, not a treatment trial. The device may not be as reliable as standard equipment, and results may not apply to all patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.
