This work aims to evaluate the performance of various blood pumps used in extracorporeal life support (ECLS).
Manufacturers provided ECLS consoles and pump samples for testing.
Pumps were assessed in a mock-loop measuring volume flow and pressures at different preload and afterload levels.
Eight different ECLS pumps were tested, including both centrifugal and diagonal designs.
Performance curves were generated for both pediatric and adult ECLS pumps.
Six centrifugal pumps and two diagonal pumps were tested across their operational ranges.
Key design features impacting pump performance and their implications for clinical use were discussed.
