Ultra-protective Ventilation Monitored by Electrical Impedance Tomography in Patients With Severe Acute Respiratory Distress Syndrome on Veno-venous ECMO
For ECMO supported patients with severe ARDS (acute respiratory distress syndrome), usual care include use of ultraprotective mechanical ventilation with tidal volume and pressure reductions that might ultimately enhance lung protection of patients with ARDS. Although very low tidal might also cause pulmonary derecruitment. The aim of this study is to monitor effects of very low tidal volume on regression of overdistension and derecruitment using electrical impedance tomography. Secondary aim is to describe the evolution of the optimal PEEP (Positive End Expiratory Pressure) during the decrease of the tidal volume
