Assessing lung overdistension in ARDS patients using Electrical Impedance Tomography

Pulmonary Overdistension Assessment With Electrical Impedance Tomography in Patients With Acute Respiratory Distress Syndrom in Prone Position

Observational University Hospital, Bordeaux · NCT06536543

This study is testing how to find the best breathing support settings for patients with severe lung issues by using special technology to see how well their lungs are working while they are on a ventilator.

What this trial studies

This observational study focuses on patients with Acute Respiratory Distress Syndrome (ARDS) who are intubated and sedated. It aims to evaluate the optimal level of Positive End-Expiratory Pressure (PEEP) during mechanical ventilation by using Electrical Impedance Tomography (EIT) to measure lung ventilation distribution. The study will assess the balance between lung recruitment and the risk of overdistension in both prone and non-prone positions. Patients will be monitored in the ICU to determine the best PEEP settings for their condition.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who are hospitalized in the ICU with moderate to severe ARDS.

Not a fit: Patients with broncho-pleural leaks, pregnant or breastfeeding women, or those with contraindications to EIT will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved ventilation strategies for ARDS patients, potentially reducing lung injury and improving outcomes.

How similar studies have performed: While the use of EIT in assessing lung ventilation is gaining traction, this specific approach to optimizing PEEP in ARDS patients is relatively novel and has not been extensively tested.
