      Extracorporeal membrane oxygenation device is a procedure in which mechanical systems circulate blood and supplyoxygen to patients with impaired cardiopulmonary function. Current venoarterial systems are associated with low patientsurvival rates and new treatments are needed to avoid left ventricular dilation, which is a major cause of death. In thisstudy, a new mobile pulsatile ECMO with a pump structure that supplies pulsatile flow by using an oxygen tank as a powersource is proposed. In vitro experiments conducted under mock circulation system as like patient conditions demonstratedthat 2.8 L oxygen can sustain the outflow of 1 L/min of pulsatile blood flow for 53 min, while a 4.6 L tank was able tosustain the same flow for 85 min. The energy equivalent pressure evaluation index of the pulsatile blood pump showsthat the mobile pulsatile ECMO could supply sufficient pulsatile blood flow compared to the existing pulsatile ECMO.
      Through in vitro experiments performed under mock circulation conditions, this new system was proven to supply sufficientoxygen and pulsatile blood flow using the pressure of an oxygen tank even while transporting a patient.
