Extracorporeal Life Support Organization (ELSO)

World's Largest ECMO Patient Registry and Largest Community of ECMO Centers

ELSO was founded in 1989 by Robert H. Bartlett, MD, who is credited with developing extracorporeal membrane oxygenation (ECMO) in the 1960s and ’70s.

About ELSO

The Extracorporeal Life Support Organization (ELSO) is an international nonprofit consortium of health care institutions, researchers, and industry partners. We provide support to those delivering extracorporeal life support through continuing education, guidelines, original research, publications, and a comprehensive registry of extracorporeal membrane oxygenation (ECMO) patient data.

What Is Extracorporeal Membrane Oxygenation (ECMO)?

Learn all about extracorporeal membrane oxygenation (ECMO), which is a common treatment in acute respiratory distress syndrome (ARDS), COVID-19, and other critical care situations. Although ECMO may not cure the patient, it gives him or her a chance to heal by giving their heart and lungs time to rest.

Updates to Equipment Recall Information:

We have updated our ECMO Equipment Updates page to reflect the latest activities regarding equipment recalls.
Specifically, there is a new letter from the FDA issued May 8, 2024. Getinge has updated their response to the updated recall notice, with specific messages for the US and outside of US markets. Both notices can be found on the equipment updates page. Other device manufacturers are updating their information as well.
ELSO continues to work with our centers, regulatory agencies, and device developers to advocate for adequate access to ECLS equipment. If you have additional questions or recommendations, please send them to support@elso.org.
