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 Results may not be published yet.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

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 heart rate variability (small changes in heartbeat timing) can help doctors decide the best time to remove a breathing tube from critically ill patients. About 100 adults on ventilators will have their heart signals and standard weaning tests combined into a new prediction model. The goal is to reduce failed extubations and improve outcomes like days off the ventilator and ICU stay length.

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

Inclusion Criteria: * Age between 18 and 85 years. * Received mechanical ventilation for more than 24 hours and clinically assessed as ready for a Spontaneous Breathing Trial (SBT). * Stable ECG signal quality before extubation, meeting the basic requirements for HRV analysis. * Obtained informed consent from the patient or their legal representative, and agreed to participate in this study and cooperate with the 72-hour follow-up after extubation. Exclusion Criteria: * Individuals with permanent pacemakers, defibrillators, or other devices that affect monitoring data. * Individuals on continuous deep sedation (RAS ≤ -4) and unable to regain consciousness in the short term. * Individuals with severe arrhythmias or unstable cardiovascular conditions that prevent reliable HRV analysis. * Individuals with cognitive impairment or mental illness that prevents them from cooperating with the research process, or individuals deemed unsuitable for participation in this study by their clinicians.
