Optimizing mechanical ventilation for morbidly obese patients with ARDS

Official title: Transpulmonary Pressure - Guided Mechanical Ventilation in Morbidly Obese ARDS Patients: a Feasibility Study.

Run by Assistance Publique - Hôpitaux de Paris · NCT06119516 · Data updated 2026-11-12

This study is testing if adjusting breathing machine settings based on pressure measurements can help morbidly obese patients with severe lung problems breathe better than standard methods.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with class III morbid obesity and moderate to severe ARDS.

Probably not a fit

Patients with contraindications to nasogastric tubes or those on life-sustaining therapy limitations may not benefit from this study.

What this trial studies

This clinical trial aims to personalize mechanical ventilator settings for morbidly obese patients suffering from moderate to severe Acute Respiratory Distress Syndrome (ARDS). It utilizes esophageal pressure measurements to guide adjustments in ventilator settings, potentially improving patient outcomes by preventing fluid accumulation in the lungs. The study will compare the effectiveness of this personalized approach against standard strategies used in ARDS management. Participants will be monitored using a nasogastric probe to measure esophageal pressure, which serves as an indicator of pleural pressure.

Why it matters

Potential benefit: If successful, this approach could lead to improved respiratory function and outcomes for morbidly obese patients with ARDS.

How similar studies have gone: While the approach of using esophageal pressure monitoring is innovative, similar studies have shown promise in optimizing mechanical ventilation strategies.
