New imaging technique may help ventilator settings for lung injury patients
NCT ID NCT05825534
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a non-invasive imaging method called electrical impedance tomography (EIT) to measure airway opening pressure in 6 adults with acute lung injury or ARDS. The goal was to see if EIT could detect where and when small airways open during a slow breath, which might help doctors set ventilators more precisely. The study was completed and focused on understanding lung behavior, not on testing a new drug or treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could improve how doctors set ventilators for patients with lung injury, potentially reducing further lung damage.
- What could go wrong
- This is a very small, early study with only 6 participants, so results may not apply to all patients. It is observational and does not test a new treatment.

Inclusion Criteria: * Adult patients (≥18 years old). * Patients with PaO2/FiO2 ratio \<300 mmHg. * Volume- or pressure-controlled ventilation. * Sedated, with or without infusion of neuromuscular blockage. * Patients in supine position Exclusion Criteria: * Pneumothorax and bronchopleural fistula. * Severe hemodynamic instability (\>30 % increase in vasopressors in the last 6 hours or norepinephrine \> 0.5 µg/kg/min). * PaO2/FiO2 ratio \< 80 mmHg. * Severe or very severe chronic obstructive pulmonary disease (COPD) according to the GOLD criteria (stage III: FEV1 30-50% predicted; stage IV: FEV1 \< 30 % predicted). * Known or highly suspected elevated intracranial pressure (\>18 mmHg). * Impossibility to correctly position the EIT belt (e.g., burns chest drainage, etc.). * Contraindications to EIT (e.g., implantable cardiac defibrillator, pacemaker, instable spinal lesions, etc.). * Clinical judgement of the attending physician. * Pregnant or breastfeeding woman * Patient under guardianship, curators or safeguard of justice
