What are the water fibers in ECMO systems called?

• A. Polyester
• B. Polyethylene
• C. Polyurethane
• D. Polysulfone

Answer: (C)

In ECMO systems, the water fibers referred to are typically made from polysulfone. Polysulfone is a type of polymer known for its excellent biocompatibility and mechanical strength. It is frequently used in the construction of hollow fiber membranes for medical applications, including those involved in ECMO circuits, due to its ability to facilitate gas exchange while resisting clot formation. Polysulfone fibers allow for high surface area and permeability, which are critical for efficient oxygenation and carbon dioxide removal in patients requiring ECMO support. This material ensures optimal performance in managing the patient's respiratory and circulatory needs during treatment. The use of polysulfone fibers is particularly advantageous in maintaining the integrity and functionality of the ECMO circuit over prolonged periods.
