Authors' conclusion

In this study, 4.7% of ARDS patients with venovenous ECMO underwent a mode escalation. Escalation was independently associated with higher in-hospital mortality, an association that may be partially confounded by low hospital's venovenous ECMO volume. Among the modes after escalation, venoarterial ECMO was associated with a significantly higher survival rate.
