The ECMO-Free Trial

"All patients randomized to the ECMO-Free Protocol Group will receive a protocolized daily assessment of readiness for liberation from VV-ECMO, which will be initiated between 6:00 AM local time and 10:00 AM local time. If the patient is enrolled after 10:00 AM local time the ECMO-free protocol will begin the following calendar day.~The ECMO-Free Protocol is a 3-step process of assessing readiness for liberation from VV-ECMO: a safety screen (Phase 1: ECMO-Free Safety Screen), titration of the non-ECMO fraction of inspired oxygen (Phase 2: Non-ECMO respiratory support titration), and a trial of cessation of sweep gas flow (Phase 3: ECMO-Free Trial)."

All patients randomized to the Usual Care Group will undergo assessments of readiness for liberation, weaning, and decannulation at the discretion of the treatment team.
