Identification of regional overdistension recruitment and cyclic alveolar collapse with electrical impedance tomography in an experimental ARDS model

摘要

BackgroundInformation on regional ventilation distribution in mechanically ventilated patients is important to develop lung protective ventilation strategies. In the present prospective animal study, we introduce an electrical impedance tomography (EIT)-based method to classify lungs into normally ventilated, overinflated, tidally recruited/derecruited and recruited regions.
