Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study investigates the influence of a clinically indicated fluid challenge on end-expiratory lung impedance, assessed by electrical impedance tomography (EIT). EIT data will be collected before, during and after infusion of 500 ml of crystalloid solution in mechanically ventilated patients on an operative intensive care unit.
