A: Basic connectivity of ad hoc ECMO composed from Impella pumps and standard oxygenators. B, C: pieces and assembly of Impella CP-based ECMO system. D,E: pieces and assembly of Impella 5.0-based ad-hoc ECMO system. F: closed-loop setup for pump testing, was run for 48 hours and showed stable performance. G: venous access cannulas; .....
    Document: the author/funder, who has granted medRxiv a license to display the preprint in perpetuity. Figure 1 : Ad-hoc ECMO. A: Basic connectivity of ad hoc ECMO composed from Impella pumps and standard oxygenators. B, C: pieces and assembly of Impella CP-based ECMO system. D,E: pieces and assembly of Impella 5.0-based ad-hoc ECMO system. F: closed-loop setup for pump testing, was run for 48 hours and showed stable performance. G: venous access cannulas; the 25F and 22F cannula were used in F. F: closed loop system including Impella pump, venous drainage and return cannulas, oxigenator module; to simulate oxygen extraction by a patient, an additional gas exchange module (flused with N2) is added. 48 hourtesting of this setup with reconstituted blood showed stable flows, and stable gas exchange. Impella CP, level 9
