Influence of Different PEEP Levels and Tidal Volumes on Regional Lung Function

Mechanical ventilation is indispensable for most of surgical interventions but can induce lung injury even in pulmonary healthy patients. This can lead to postoperative pulmonary complications. These adverse effects could be prevented by a better monitoring of intraoperative lung function. Electrical impedance tomography is able to visualize aeration within the lung in real time. The planned study investigates the influence of different levels of positive endexspiratory pressure and different tidal volumes on the aeration.
