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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 looks at 100 COPD patients on breathing machines to see if a new ultrasound-based method (D-RSBI) is better than the standard method (RSBI) at predicting when they can safely breathe on their own. Researchers will measure both methods during a breathing trial and check if patients stay off the machine for 72 hours. The goal is to improve weaning success and reduce failed extubations.

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 more accurately decide when to remove breathing tubes in COPD patients, reducing complications.
What could go wrong
This is a small, early observational study (100 people) that only measures prediction accuracy, not a treatment. Results may not apply to all patients.

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

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Mechanically ventilated COPD patients fulfilling standard weaning readiness criteria. * Invasive mechanical ventilation for more than 24 hours before spontaneous breathing trial. * Hemodynamically stable without significant vasopressor support. * Adequate oxygenation with FiO2 ≤ 0.5 and PEEP ≤ 8 cmH2O . * Preserved mental status and ability to initiate spontaneous breathing. * Successful tolerance of spontaneous breathing trial conducted on CPAP mode with pressure support ≤ 8 cmH2O. Exclusion Criteria: * Refusal of consent * Neuromuscular disease, phrenic nerve palsy, or diaphragmatic paralysis. * Large pneumothorax or pathology interfering with ultrasound assessment. * Terminal extubation. * Recent major thoracic surgery. * Poor sonographic window despite repeated attempts.
