Can a patient recover from ECMO?

Could you please elaborate on the likelihood of a patient fully recovering after undergoing Extracorporeal Membrane Oxygenation (ECMO) therapy? What factors influence the recovery process, and what measures can be taken to enhance the chances of a successful outcome? Are there any potential long-term effects or complications that patients and their families should be aware of? Additionally, what kind of support or follow-up care is typically required post-ECMO to ensure optimal recovery?
