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 Results may not be published yet.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.

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 lying on your left side, right side, or back affects lung function in adults with acute respiratory distress syndrome (ARDS) after abdominal surgery. Researchers will use a special imaging technique called electrical impedance tomography to measure how well air and blood flow match in the lungs. The goal is to find out which position might help patients breathe better.

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 the best body position to improve breathing in patients with ARDS after abdominal surgery.
What could go wrong
This is a small, early-stage study with only 24 participants, so results may not apply to all ARDS patients. It focuses on measuring lung function, not on finding a treatment.
