Ultra-protective Pulmonary Ventilation Supported by Low Flow ECCO2R for Severe ARDS

Overview

This study evaluates the use of ultra-protective ventilation, where very low ventilation volumes are used, in patients with severe acute respiratory distress syndrome (ARDS) meeting criteria to nurse in the prone position. Half the patients will receive ultra-protective ventilation support by extracorporeal carbon dioxide removal, while the other half will receive conventional lung protective ventilation.

Current best practices for management of severe ARDS include lung protective ventilation and nursing in the prone position. However, the best lung protective strategy is not currently established and using smaller ventilation volumes than standard lung protective ventilation suggest lung recovery is improved. Application of smaller ventilation volumes requires extracorporeal carbon dioxide removal, using a device similar to a dialysis to remove carbon dioxide directly from the blood. One such device in the Prismalung, it removes blood through a catheter, much like a dialysis catheter, pumps it through a gas exchange cartridge which removes carbon dioxide. The gas exchange cartridge functions in a similar way to a dialysis filter, except it allow gases to pass through, unlike dialysis filters which allow passage of fluid and small molecules.
