Clinical comparison between four modern membrane oxygenators: Bentley CM 40/50, COBE CML, Sci Med 3500-2A and Travenol LPM 50.
The devices with flat polypropylene membranes can be primed simpler and faster, than devices with the capillary membranes or with silicone rubber membranes. These two devices also offer more protection against venous air admixture and leaking of bubbles across the membrane. From hematologic standpoint there was no clear advantage of one particular device over another.
