Northwestern Medicine Extracorporeal Membrane Oxygenation (ECMO) Program

Northwestern Medicine provides extracorporeal membrane oxygenation (ECMO), or extracorporeal life support, to patients with life-threatening illness or injuries that prevent their lungs or heart from working effectively. With the veno-venous ECMO (VV-ECMO), the machine removes blood from the body, oxygenates it and returns it to the body, acting as artificial lungs. This allows the patient’s lungs to rest and provides more time for medical treatments to address the underlying condition. VV-ECMO itself is not a direct treatment; it serves as a “bridge” on the way to medical improvement or a lung transplant.

Most patients who need VV-ECMO require the ongoing assistance of a ventilator. To prepare the body for VV-ECMO, a surgeon places plastic tubes called cannulae into two large veins for blood exchange. Patients are given pain medications to keep them comfortable during this procedure. Once the tubes are in place, they are not painful. When the VV-ECMO machine is running, the non-oxygenated blood being removed from the body is dark red in color. After the blood is oxygenated by the machine, its color during its return to the body is bright red.

After VV-ECMO begins, most patients remain sedated. However, with time, some patients may no longer require sedation to be comfortable, at which point they may wake up and be able to interact with people. In some cases, patients may be able to participate in exercises to build their strength while on the VV-ECMO machine.

At Northwestern Medicine, we have assembled an extraordinary team of specialists to care for patients and families during this time of acute illness.

Areas of Care

History of ECMO

ECMO technology was developed in the 1960s to serve as a long-term "bypass machine" to support the lungs or heart.

Veno-Venous Versus Veno-Arterial ECMO

There are two main types of ECMO support.

When VV-ECMO Is Needed

The main reason to use VV-ECMO therapy is severe lung failure that cannot be treated by medications and a breathing machine.

After VV-ECMO

VV-ECMO is used to give the lungs an opportunity to heal or, in some cases, as a support while waiting for lung transplantation.

Potential Complications

Potential complications related to VV-ECMO can arise.

Role of the Family

If you have a loved one on VV-ECMO, you have an important role in their care, and we want you to be able to spend time with them.

VV-ECMO and COVID-19

Approximately 5% of patients with COVID-19 develop critical lung disease that requires a breathing tube and ventilatory support.
