Could 40 hours on your belly save more lives from lung failure?
NCT ID NCT07126964
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether keeping patients with severe lung failure (ARDS) on their stomachs for 40 hours at a time, instead of the usual 16 hours, can lower the chance of death. About 800 adults on breathing machines will be randomly assigned to one of the two positions. The goal is to see if the longer belly-down approach improves survival at 28 days.

Inclusion Criteria: Age of 18 years * Admitted to ICU. * Under invasive ventilation for a maximum of 5 days. * Meeting the 2012 Berlin criteria for ARDS * Protective ventilation at time of inclusion : 1. Plateau pressure \< 35 cm of H2O at the time of screening 2. VT ≤ 8 ml/kg PBW on all nurse's charts before inclusion 3. PEEP ≥ 5 cm H2O on all nurse's charts before inclusion c. Twice daily blood gas while FiO2 ≥ 60% before inclusion * PaO2/FiO2 ≤ 150 mmHg with FiO2 ≥ 60% and Spo2 between 92 and 96% after optimization by setting PEEP to 10 mmHg, sedation levels optimization and, if necessary, administration of neuromuscular blockers to ensure patient-ventilator synchrony, with VT ≤ 8 ml/kg PBW and Pplateau \< 30 cm H2O. Exclusion Criteria: * PP during the same ICU stay and before inclusion, ECMO before PP, arterio-venous ECMO * persistent PaO₂/FiO₂ ratios \<150 mm Hg, with FiO2 ≥ 60% on all arterial blood gases collected over a 24-hour period without this prompting study inclusion * Spine instability, intracranial pressure \> 20 mmHg, severe brain injury, hemodynamic instability deemed to contraindicate PP by the physician in charge * Home oxygen supplementation * Care limited to comfort measures only * Inclusion in another interventional study including mechanically ventilated patients, which intervention concerns PP and for which mortality à D28 or D30 is the main outcome studied. * Already included in PROSECO * Pregnancy, subject deprived of freedom, Person under conservartorship, no insurance * Refusal to participate expressed by the patient or his/her healthcare proxy or a close relative if present
