Research Progress on Influence of Centrifugal Blood Pump on Blood Injury

Centrifugal blood pumps drive blood flow by regulating blood flow rate, and have been widely used in clinical applications, including extracorporeal membrane oxygenation (ECMO), cardiopulmonary bypass (CPB), and extracorporeal circulation carbon dioxide removal (ECCO₂R). However, because different structures and different forms of centrifugal pumps have different requirements for blood extracorporeal circulation in clinical application scenarios, blood pumps face different application conditions in clinical use. In this study, the effects of different structures of centrifugal pumps and different working conditions on blood damage are summarized for reference by relevant institutions and R&D personnel.
