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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study tested whether a special imaging method called electrical impedance tomography (EIT) can help doctors choose the best ventilator settings for patients with severe lung injury (ARDS). The goal was to see if EIT could identify which patients would benefit from higher or lower pressure settings, and to spot those at higher risk. The study involved 120 critically ill patients on ventilators. The findings may lead to safer, more personalized breathing support in the ICU.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

This study included adult patients (≥18 years) with moderate-to-severe acute respiratory distress syndrome (ARDS) who were receiving invasive mechanical ventilation in the intensive care unit (ICU) of Ruijin Hospital. All enrolled patients met the Berlin definition of ARDS and had a PaO₂/FiO₂ ratio ≤200 mmHg within 6 hours of screening. A total of 120 patients were consecutively enrolled from December 2022 to December 2024. Patients were stratified by airway closure status for subgroup analyses.
