Plain-language summary
The CALMDOWN trial is a prospective, open-label, multicenter, comparative, controlled trial randomizing patients who received near apneic ventilation vs usual care on ECMO (ultra-protective lung ventilation).
The study goal is to investigate the benefit of early apneic ventilation in the most severe forms of acute respiratory distress syndrome (ARDS) rescued by ECMO.
Indeed, our hypothesis is that that early (near) apneic ventilation on venovenous ECMO for severe ARDS can enhance ventilator injury prevention and therefore reduce ECMO duration and mortality at Day 60.

Inclusion criteria
✓. Severe acute respiratory distress syndrome refractory to conventional therapy placed on VV-ECMO support in the 48 hours (maximum tolerance : +2h) preceding inclusion.
✓. Obtain informed consent from a close relative or surrogate. According to the specifications of emergency inclusion, randomization without the close relative/surrogate consent could be performed if the patient is unable to give his/her consent and when the close relative/surrogate/family member are absent. Close relative/surrogate/family member consent will be asked as soon as possible after randomization. The patient will be asked as soon as possible to give his/her consent for the continuation of the trial when his/her condition will allow.
✓. French Social security registration (except AME)

✕. Cardiac arrest with cumulated no flow time \&gt;10 minutes before ECMO (within 48 hours prior to inclusion)

What they're measuring
1
Efficacy of the application of early apneic ventilation on four components : mortality status at D60, need for lung transplantation at D60, persisting ECMO at D60, number of days alive between randomization and day 60 without ECMO
