First Things First

  • Extracorporeal membrane oxygenation (ECMO) is a form of cardiopulmonary bypass used for support of respiratory and/or cardiac function in patients with reversible cardiopulmonary failure.
  • Components of ECMO
    • Drainage cannulas
    • Pump
    • Oxygenator
    • Heat exchangers
    • Tubing
    • Return cannulas
  • Blood flows of 50-100 ml/kg/min can be provided.
  • PaCO2 is determined by the oxygenator gas flow (or sweep speed)
  • PaO2 is determined by the amount of flow through the circuit and amount through the lungs.
