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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 test a new, non-invasive method called EIT Pulse Wave to measure blood flow to the lungs and predict heart stroke volume in critically ill patients. Researchers will compare it to the standard Swan-Ganz catheter, which is invasive. The study involves 19 adults in the ICU who are already on a ventilator and have a Swan-Ganz catheter in place. Measurements will be taken every 30 minutes for up to 48 hours.

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 a non-invasive way to monitor heart function in critically ill patients, reducing the need for invasive catheters.
What could go wrong
This is a very small, early observational study with only 19 participants, so results may not apply broadly. The EIT method may not be accurate enough to replace standard monitoring.

Who can take part

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

Who is studied

The study population consists of critically ill adult patients admitted to the Intensive Care Unit of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. All participants require mechanical ventilation support and meet either the 2023 global ARDS diagnostic criteria and/or are receiving vasoactive medications for shock treatment. A key inclusion prerequisite is that patients must already have a Swan-Ganz catheter inserted for clinical hemodynamic monitoring purposes. Study subjects will undergo simultaneous non-invasive EIT monitoring and invasive catheter measurements to evaluate the correlation between the two methods in measuring stroke volume.
