There is the maneuver done on HFOV in the IN-REC-SUR-E trial. could be adapted to CMV shouldn't be much different. I don't think there is a solid recruitment maneuver out there for the neonatal population. None of the parameters (LUS, dyn Cyn changes) have been widely accepted yet. Simply put... I don't think we really know what's the optimal PEEP and how to set it.
