Semi-Empirical Model to Predict Blood Flow in an Extracorporeal Respiratory Support Circuit Driven by Ventricular Assist Devices

Abstract Despite increasing clinical interest in ambulatory extracorporeal membrane oxygenation (ECMO), its equipment is not optimally designed for portability. Blood pumps are too heavy for ambulation, as the lightest system..

Impact of different blood flow modes on hemodynamic environment, thrombosis risk and oxygen transport of oxygenators: A numerical simulation study

Abstract Background and Objective Pulsatile blood flow is considered more potential for delivering hemodynamic energy and enhancing microcirculatory perfusion in patients compared to non-pulsatile flow in ECMO. This study aims..

Increasing Anticoagulation Intensity in the Oxygenator During Flow Reduction Trials in Venoarterial Extracorporeal Membrane Oxygenation

Abstract Anticoagulation is mandatory during venoarterial extracorporeal membrane oxygenation (V-A ECMO) flow reduction trials with very low blood flow. Anticoagulation in the ECMO circuit might be intensified with less effect..

Impact of Cannulation Strategy and Extracorporeal Blood Flow on Recirculation During Veno-Venous Extracorporeal Membrane Oxygenation

Abstract Introduction Veno-venous extracorporeal membrane oxygenation (V-V ECMO) is increasingly used in the treatment of severe respiratory failure. Despite a significant increase in the worldwide use of extracorporeal lung assist..

Effect of hollow fiber configuration and replacement on the gas exchange performance of artificial membrane lungs

Abstract Artificial membrane lungs are composed of hollow fiber membranes. Blood flows with low velocities in the membrane bundle, forming a laminar boundary layer near the membrane surfaces that limits..

Blood flow but not cannula positioning influences the efficacy of Veno-Venous ECMO therapy

Abstract Despite being vital in treating intensive-care patients with lung failure, especially COVID-19 patients, Veno-Venous Extra-Corporeal Membrane Oxygenation does not exploit its full potential, leaving ample room for improvement. The..
