Study aims to predict breathing response in lung injury recovery
NCT ID NCT04524091
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at patients recovering from acute respiratory distress syndrome (ARDS) who are on a breathing machine. Researchers want to see if increasing the pressure in the ventilator (called PEEP) can reduce the effort patients need to breathe on their own, which may protect their lungs from further injury. The study will measure lung stiffness and breathing patterns to find a simple way to predict who benefits from higher pressure. About 30 adults on ventilators will take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Need of invasive mechanical ventilation * Patients who had fulfill ARDS criteria based on Berlin definition during any time of invasive mechanical ventilation. * Patient ventilated in pressure support ventilation. * Time of invasive ventilation expected to be longer than 24 hs after the day of enrollment. Exclusion Criteria: * Neuromuscular diseases (e.g., amyotrophic lateral sclerosis, Duchenne Erb) * previous diagnosis of chronic obstructed pulmonary disease * not resolved pneumothorax * bronchopleural fistula * suspicion of central respiratory drive alteration (e.g., benzodiazepines intoxication).
