Extracorporeal Life Support Organization

Thank you for helping ELSO disseminate information by entering your experience in the ELSO Registry as soon as ECMO is implanted - before the run is complete. Instructions for entering data in the Registry and COVID-19 addendum can be found on the Data Definitions page.

We recognize you cannot complete and submit the entire ELSO Registry case report form prior to completion of the ECMO run and discharge from the hospital, but we would still like to have the data you know now.

To address concerns about incomplete data we report three nested data sets to accommodate the fact that different patients will be at different stages of care (and thus have more or less incomplete data). Also when considering the data please understand that the data displayed is a real-time data stream and subject to change as more patient information is accrued and as centers update the ELSO Registry Case Report Form and the ELSO COVID-19 addendum.
