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 Results may not be published yet.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.

Summary

This study looks at how different ventilator pressure settings affect breathing and heart function in people with COPD undergoing lung surgery. Forty-eight patients will each try three short pressure settings in random order. The goal is to find which setting keeps the lungs open and the heart stable.

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 help doctors choose better ventilator settings during lung surgery for COPD patients, potentially improving safety and outcomes.
What could go wrong
This is a small, early-stage study with only 48 participants, so results may not apply to all patients. It measures short-term effects, not long-term benefits or risks.

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

Participants

About 48 people

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

Started
