In cardiac surgery, maintaining proper oxygenation of blood is critical for patient safety and successful outcomes. Membrane oxygenators, often referred to as oxygenators for CPB (cardiopulmonary bypass), play a pivotal role in supporting the heart and lungs during these procedures. Understanding their use and operational requirements helps hospitals and surgical teams maximize both efficiency and safety.

The efficacy of a membrane oxygenator, a core component in cardiopulmonary bypass (CPB) systems, depends fundamentally on the advanced materials from which it is constructed. These components must achieve a critical balance: facilitating highly efficient gas exchange while minimizing any adverse reaction with the patient’s blood. The evolution of these devices is, in many ways,
