Commercially available Hollow Fiber (HF) based Extracorporeal Membrane Oxygenators (ECMO) are presently being built using a parallel assembly of over 10- 20K of porous hollow polymeric fibers as respective reactor core elements (RCE). They are currently being used during cardiopulmonary bypass or cardioplegic surgery to provide the function of a lung. The external blood circuit is driven by a blood pump while using pure O2 as the sweep gas. We have analyzed ECMO designs for both pure O2 and Air sweep gas operation and found that the novel ECMO designs incorporating c-VACNTTM – RCE’s have the potential to reach the goal of building ECMO devices that could eventually operate at a similar performance level as conventional HF based devices, but use Air instead of pure O2 as the sweep gas. We have also developed a non- destructive test system that allows optimization of various designs and evaluation of their potential for EMCO usage.
