EIT Assessment of Overdistension in ARDS Patients in Prone Position
Trial Parameters
Brief Summary
Mechanical ventilation in ARDS requires protective ventilation with low VT and PEEP. PEEP titration can improve lung recruitment in the dependent lung but with a risk of overdistension in the non-dependant lung. EIT can measure the distribution of tidal ventilation and assess overdistension and collapse during a PEEP titration in any position (prone or not). This study aims to measure the best PEEP as a compromise between recruitment and overdistension during a PEEP trial with EIT before and just after PP.
