New study aims to personalize ventilator settings for lung injury patients
NCT ID NCT07603310
First seen Jun 27, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study looks at two different methods for setting the pressure on a breathing machine (ventilator) in people with a serious lung condition called ARDS. The goal is to see which method improves oxygen levels better over 24 hours. About 52 adults with moderate to severe ARDS will take part. The findings may help doctors choose the best ventilator settings for each patient.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Diagnosis of moderate or severe Acute Respiratory Distress Syndrome (ARDS) according to the Berlin definition: acute onset, bilateral opacities not fully explained by heart failure or fluid overload, and Partial pressure of oxygen in arterial blood/Fraction of inspired oxygen \<= 200 mmHg with Positive End-Expiratory Pressure (PEEP) \>= 5 cmH2O. * ARDS duration \< 36 hours since fully meeting Berlin consensus criteria. * Relative hemodynamic stability: absence of refractory shock, defined as norepinephrine dose \<= 0.5 mcg/kg/min. Exclusion Criteria: * Evidence of active pulmonary air leaks (bronchopleural fistula, pneumothorax, pneumomediastinum). * Severe uncorrected hemodynamic instability (norepinephrine \> 0.5 mcg/kg/min). * Contraindications for esophageal balloon placement (esophageal obstruction, known perforation, recent esophageal surgery, severe esophagitis). * Elevated intracranial pressure or conditions where hypercapnia-induced increases in intracranial pressure must be avoided (intracranial hemorrhage, cerebral contusion, cerebral edema, mass effect with midline shift on CT). * Known pregnancy. * Severe coagulopathy (platelet count \< 5,000/uL or INR \> 3). * Airway opening pressure higher than 15 cmH2O (AOP \> 15 cmH2O). * History of severe neuromuscular disease or chronic respiratory disease. * Having received invasive mechanical ventilation for more than 96 hours. * Inability to obtain informed consent or refusal by the legal representative. * Contained laparotomy (open abdomen).
