4 Οκτ 2020 · Centrifugal pumps are now preferred to roller pumps as they cause less haemolysis and require less anticoagulation. This book assumes you will only use centrifugal pumps. Centrifugal pumps operate by creating a fluid vortex formed by a rapidly spinning impeller .
Centrifugal pumps used at lower flow rates than their design point may lose pump efficiency and increase the risk of hemolysis. In this study, thrombogenic properties of two ECMO pumps designed for adult and neonatal use were evaluated using simulations in different flow scenarios.
Centrifugal pump. The ECMO blood pump controls the blood flow for the patient. Many pumps exist and differ in a number of ways, e.g. design, haemo-compatibility, durability and availability. There are two basic subgroups, namely occlusive and non occlusive. Occlusive pumps are positive displacement pumps and include roller pumps.
22 Απρ 2023 · Centrifugal pumps are ideal for high-flow, low-viscosity, and lower-pressure applications, while positive displacement pumps excel in applications requiring precise flow control, high pressure, and handling of high-viscosity or shear-sensitive fluids.
Positive displacement pumps have several advantages over centrifugal pumps, including their ability to handle fluids with high viscosities and solid content and to provide a constant flow rate regardless of the pressure at the pump discharge.
Whilst centrifugal pumps are the most common type of pump installed due to their simplicity, positive displacement pumps are a solution that can handle more difficult conditions where centrifugal pumps may fail, thanks to their ability to be run at any point on their curve.
