The "prolonged" when used to describe ECMO means days or weeks. Economics are not the problem here, it is currently technologically impossible to provide ECLS for an indefinite period of time without escalating risks of complications, including immediate failure as well as issues that result in death post-decannulation. There have been individual cases where patients were put on such treatments for months and have survived, but it is in fact medically extremely risky and should not be done unless there was absolutely no other choice. "Immortality" through such a means is almost certainly going to kill you within years.

Quality of life while undergoing treatment is also entirely non-existent, trust me, you to not want to be "immortal" if it required indefinite ECMO. Unless you enjoy living in hospitals I guess.
