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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This study will use a new 3D imaging device (3D-EIT) to see if it can detect a pattern called 'cyclic on-off switching' of blood flow in the lungs of 40 adults with moderate to severe ARDS who are on mechanical ventilation. The goal is to validate whether this non-invasive, bedside tool can spot a potential cause of ventilator-induced lung injury. The study is not yet recruiting and is purely observational, aiming to improve understanding rather than test a treatment.

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 lead to better monitoring of lung injury in ventilated ARDS patients, potentially improving ventilator settings and reducing harm.
What could go wrong
This is a small, early-stage observational study with only 40 participants. It is not testing a treatment, so it may not directly improve patient outcomes.
