Preload control of the increased outflow of a dual pulsatile extracorporeal membrane oxygenator

An improved pulsatile extracorporeal membrane oxygenation (ECMO) device is needed to reduce the high risk of complications associated with existing ECMO devices, due continuous blood outflow (which reduces perfusion) and a complex structure that makes setup management difficult. This study introduces new maintain sufficient pulsatility (an “energy equivalent pressure increment” [EEPI] at least 20 %) simplify pump by removing artificial valves actuators. The hemodynamic characteristics proposed were evaluated in-vitro using MOCK system. Although has same dual pumping as ECMOs, newly applied preload control mechanism increases compared previous device.
