EIT Assessment of Overdistension in ARDS Patients in Prone Position

NCT06536543 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 20

No results posted yet for this study

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.

Conditions

  • Acute Respiratory Distress Syndrome

Interventions

OTHER

Acute Respiratory Distress Syndrom (ARDS) treated with Prone Position (PP) equipped with Electrical Impedance Tomography (EIT)

Positive End-Expiratory Pressure (PEEP) will be titrated with PEEP-EIT method as it is already done in usual care. A classical low flow Pression Volume (PV) curve will be done in order to detect airway closure and measure compliance, the acquisition of EIT data during PV curve will be analysed secondary with a dedicated software. Reconstruction of EIT derived PV curve will determine the regional airway opening pressures and compliances of the 2 lungs. Two decremental PEEP-EIT titrations will be compared, one in supine and the other just after turning in prone.
