Power Dissipation in Flow-controlled Ventilation

Evone (Ventinova Medical B.V., Eindhoven, The Netherlands) is a ventilator, which is able to perform flow-controlled ventilation (FCV). Moreover it provides direct tracheal pressure measurements and combined with the constant gas flow of FCV a precise determination of dynamic compliance is feasible. Thus not only PEEP but also peak pressure can be titrated based on dynamic compliance. Additionally intratracheal pressure-volume loops can be measured and thus power dissipation calculated, which represents the primary outcome parameter of this trial.
