In recent years,the application of venovenous extracorporeal membrane oxygenation(V-V ECMO)has rapidly increased.With the evolution of new technologies,equipment and treatment,and the update of research evidence,the management in its application has become increasingly mature and standardized.The management of V-V ECMO primarily encompasses oxygen supply and consumption management,mechanical ventilation strategies,prone position treatment,awake ECMO,early rehabilitation,and standardized weaning procedures.
