Figure 2.
General flow path of blood through the Quadrox iD and NovaLung iLA devices (left). These devices employ an orthogonal flow path for the other medium (right). Blood flow is around the fibers while gas flow is through polymethylpentene fibers (Quadrox and NovaLung) and water flows through a separate set of polypropylene fibers (Quadrox only) in the right half of the oxygenator. The fibers are separated by a plastic divider (red vertical line in the left image).
