Using noninvasive breathing support for severely obese patients after extubation

Official title: A Randomized Controlled Trial of Postextubation Use of Noninvasive Respiratory Support in Severely Obese Patients

Run by Rush University Medical Center · NCT05918575 · Data updated 2026-11-12

This study is testing if using a combination of noninvasive breathing support methods can help severely obese patients breathe better after being taken off a ventilator and reduce the chances of needing to be put back on one.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with a BMI of 40 kg/m2 or higher who are undergoing planned extubation after at least 24 hours of invasive mechanical ventilation.

Probably not a fit

Patients who may not benefit from this study include those with chronic tracheostomy, terminal extubation, or contraindications to noninvasive ventilation.

What this trial studies

This clinical trial investigates the effectiveness of noninvasive ventilation (NIV) alternating with high flow nasal cannula (HFNC) in reducing the risk of respiratory failure in severely obese patients who have been extubated. The study aims to determine if this approach can lower the need for reintubation compared to using HFNC alone. Patients eligible for the trial are those who have been on mechanical ventilation for at least 24 hours and have a body mass index (BMI) of 40 kg/m2 or higher. The trial will assess the outcomes of these interventions in a randomized controlled format.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the rates of reintubation and improve recovery outcomes for severely obese patients.

How similar studies have gone: Previous smaller studies have shown that noninvasive respiratory support can reduce reintubation rates in obese patients, suggesting potential success for this approach.
