Artificial Lung Technology (ECMO)

When a person’s heart and lungs no longer function properly or need a break to recover from a serious illness, a mechanical method known as ECMO may be used to keep them alive.

ECMO, or extracorporeal membrane oxygenation, pumps blood through a device that adds oxygen to it and then pumps it back into the patient’s body, performing the function of the heart and lungs. ECMO, which can be used for both adults and children, provides long-term management of heart and/or lung failure while the patient recovers or awaits a transplant or ventricular assist device.

ECMO is sometimes also called ECLS, or extracorporeal life support.

  • Indications

    ECMO is ideal for patients whose cardiovascular health is compromised, who are at a high risk of dying, or who would not be able to maintain their current physical status if they were placed on traditional mechanical ventilation. ECMO can be used while the patient is awake, alert and able to move around, which greatly reduces the risk for complications related to immobility and ventilator use. Patients with acute respiratory distress syndrome (ARDS) or cardiogenic shock who do not have multisystem organ failure are among those who qualify for ECMO. Providers may use a variety of criteria to determine whether a patient is a good candidate for ECMO.

  • How ECMO technology works

    ECMO can be used in two different ways – venovenous (VV) and venoarterial (VA).

    Venoarterial (VA) method

    Venoarterial ECMO takes blood from a central vein or the right atrium of the heart and pumps it past an oxygenator worn outside the body. The blood then returns under pressure to the aorta to be pumped out to the body. This method helps support the amount of blood that is pumped by the heart (cardiac output).

    Venovenous (VV) method

    Venovenous ECMO takes deoxygenated blood from a large vein, passes it through the oxygenation process and returns it to the body through another large vein. This form does not support cardiac output of the heart but it allows for the removal of carbon dioxide through the oxygenator unit and doesn’t just add oxygenated blood alone.

    Patients receiving ECMO will have a large catheters (tubes) placed in the body to remove and replace the blood volume after gas exchange. Because of the risk of blood clots, patients on ECMO are given anticoagulant drugs (blood thinners) to reduce the risk of clot formation and complications.

    ECMO has been used for decades in newborns and children with lung failure, pneumonia, meconium aspiration syndrome and other conditions. More recently, it has proven to provide beneficial support for adult patients with severe respiratory and/or cardiac failure, allowing for recovery of the heart or lungs or acting as a bridge to transplantation or ventricular assist devices.

  • Joint Commission Certification

    UK HealthCare has earned The Joint Commission’s Gold Seal of Approval™ for its ventricular assist device destination therapy program by demonstrating compliance with The Joint Commission’s national standards for healthcare quality and safety in disease-specific care. The certification award recognizes our organization’s dedication to continuous compliance with The Joint Commission’s state-of-the-art standards.

    The Joint Commission's Advanced Certification in Ventricular Assist Device Destination Therapy, developed in response to Medicare requirements, provides standards for hospitals related to:

    • Staffing and facility infrastructure to support ventricular assist device placements;
    • Participation in a national, audited registry for patients who have received mechanically assisted circulatory support devices; and
    • Volume requirements for board certified cardiac surgeons who place ventricular assist devices.
  • Adult ECMO Transport

    UK is the only center in Kentucky offering adult ECMO transport – in fact, you’d have to travel more than three hours in any direction – as far east as Charlottesville, as far north as Indianapolis, as far west as Nashville – to find another center with the same service.
