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 Results may not be published yet.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 whether ultrasound scans of the heart, lungs, and diaphragm can predict if a surgical ICU patient will successfully come off a ventilator. Researchers will collect ultrasound images and clinical data from 190 adults who have been on a ventilator for at least 48 hours. The goal is to build a model that combines these ultrasound signs to improve weaning decisions and reduce failed extubation.

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 give doctors a simple, bedside tool to better decide when to remove a ventilator, potentially reducing complications and hospital stays.
What could go wrong
This is an observational study, not a treatment trial. The model may not be accurate enough for routine use, and results may not apply to all ICU patients.

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