Flow Characterization of Maquet and Bio-Medicus Multi-Stage Drainage Cannulae During Venoarterial Extracorporeal Membrane Oxygenation
This study employs computational fluid dynamics (CFD) to analyze the flow characteristics of Maquet and Bio-Medicus drainage cannulae used in venoarterial extracorporeal membrane oxygenation (VA ECMO). Through 3D modeling and turbulence simulation, the research identifies significant differences in flow dynamics and thrombosis risk between the two cannula designs. The Bio-Medicus model, in particular, showed a higher stagnant blood volume, suggesting an increased thrombosis risk. These findings underline the importance of cannula design in optimizing VA ECMO therapy and reducing complications.
