Schmidt et al. Improved lung recruitment and oxygenation during mandatory ventilation with a new expiratory ventilation assistance device A controlled interventional trial in healthy pigs. Eur J Anaesthesiol 2018; 35:1–9


The workgroup of Schumann was the first to execute a  comparative study, evaluating a commonly applied VCV protocol with FCV mode by Evone*. This study in healthy pigs shows that FCV improves lung aeration via elevated mean tracheal pressure and consequently improves arterial oxygenation at unaltered positive end-expiratory pressure (PEEP) and peak inspiratory pressure (PIP). Moreover, these findings suggest the FCV mode provided by Evone is a new approach for protective lung ventilation.

*Note: in the study a prototype Evone and prototype Tritube were used. In this Evone prototype the FCV mode was then named EVA mode, which is functionally equal. The Tritube prototype did not have a Murphy Eye.
