Is this trial a fit for you?

Likely a good fit

Adults receiving mechanical ventilation in the ICU who are planned for extubation, hemodynamically stable, and able to undergo transthoracic echocardiography are ideal candidates.

Probably not a fit

Patients with significant valvular disease, known cardiomyopathy, inadequate acoustic windows, recent surgery within 24 hours, ongoing extracorporeal support, planned prophylactic re-intubation, or who are imminently dying are unlikely to benefit or are excluded.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, single-center observational study enrolling adult ICU patients who meet standard weaning criteria. Participants will undergo transthoracic echocardiography within two hours of readiness for extubation to measure LVOT VTI, MAPSE, E/e', E/A, mitral deceleration time, and the Tei index. Patients will be monitored for 24 hours after extubation to determine weaning success, defined as maintaining spontaneous breathing without reintubation, noninvasive ventilation, or high-flow oxygen. The study aims to identify which left ventricular systolic, diastolic, and global function parameters best predict extubation outcomes to support physiologically guided weaning decisions.

Why it matters

Potential benefit: If successful, this approach could enable clinicians to use noninvasive bedside cardiac measurements to reduce extubation failure and related complications.

How similar studies have gone: Previous observational studies have reported that echocardiographic measures such as E/e' and LVOT VTI can be associated with weaning outcomes, but findings are variable and not yet definitive.
