ELSO at a Glance

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.
