The survival rate for ECMO, especially V-V ECMO for pulmonary pu

For pulmonary purpose, I could say well over 60% in US. i think with unknown causes, it is a right decision to put the patient on ECMO, as long as it is under patient’s medical advance directive.  Too bad it failed. ECMO in China, by far still quite new to them, is not as well managed as it is here. 

And ECMO does save lives, some of whom even recover back to normal.
