Effect of positive end-expiratory pressure on regional ventilation monitored by electrical impedance tomography in mechanically ventilated ICU patients

Diederik Gommers, IG Bikker, Jan Bakker

Abstract

The optimal positive end-expiratory pressure (PEEP) is a balance between the prevention of overdistention in the nondependent part and alveolar collapse in the dependent part. Electrical impedance tomography (EIT) has been introduced to monitor regional change of ventilation at the bedside. We evaluated the effect of changes in PEEP on regional ventilation in mechanically ventilated patients with or without lung disorders.
