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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing whether adding capnography, a device that measures exhaled carbon dioxide breath by breath, to standard monitoring helps keep patients safe during endobronchial ultrasound under sedation. The study includes 100 adults scheduled for this lung procedure. Half receive standard monitoring, and half receive standard monitoring plus capnography. The team compares how often oxygen levels drop below 90% and how often airway problems occur in each group.

What this could mean

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

Active substance
capnography monitoring, a device that measures exhaled carbon dioxide breath by breath
What this could lead to
If capnography catches breathing problems earlier than standard monitoring, it could become a routine safety addition for sedated lung procedures.
What could go wrong
This is a single-center study of 100 people, so the results may not apply everywhere. Capnography adds equipment and alarms that could slow the procedure or distract the care team.

Study facts

What this study's own registry entry says, in plain language.

Phase

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

100 people

The number who actually took part.

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.

Ages

18 years and older

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
