From: Physiological and Technical Considerations of Extracorporeal CO2 Removal
 | Stacked | Wound |
---|---|---|
Advantages | −Low pressure drop through higher permeability in flow direction −Unidirectional flow −Increased convectional gas transfer through cross-layered fiber arrangement | −Countercurrent flow possible |
Disadvantages | −Inhomogeneous wash out of the corners and higher risk of thrombus formation −Allows only crosscurrent flow | −Prone to clogging through washed in debris due to its smaller cross-sectional area −Mostly long fibers and long flow path |
Examples | −iLA (Novalung, Germany) −Quadrox series (Maquet, Germany) | −Hilite product line (Medos Medizintechnik AG, Germany) −CAPIOX oxygenator (Terumo, Japan) |
