Vienna—In two studies presented at Euroanaesthesia 2019, researchers showed that flow-controlled ventilation (FCV) improved gas exchange, and that the linearized expiratory airflow during FCV may be particularly lung-protective in obese patients.
FCV is a novel type of ventilation, which delivers a constant positive flow during inspiration and maintains a constant negative flow during expiration. With FCV, pressure increases linearly during inspiration—similar to volume-controlled
