Extracorporeal Mem brane Oxygenation (ECMO) is essential in critical care for themanagement o f severe respiratory and cardiac failure. Considered the most importantpar t of the ECMO circuit\, the membrane blood oxygenator (BO) is responsible formaintaining O2 and CO2 levels in the blood.

Current BOs requi re large membranesurface areas\, but these have poor hemocompatibility\, w hich leads to activation of thecoagulation system. Despite the considerabl e progress during the last decades incomponent technology and at the circu it level\, a BO capable of performing efficientlyin prolonged ECMO does no t exist.

To improve the O2 permeability our research hasbeen foc used on the development of new blend polyurethane-based (PUR)membranes\, u sing polyether and polyester-based segmented PURs\, which exhibitenhanced hemocompatibility\, in association with a good flex-life and mechanicalstr ength..
