Before embarking on the costly task of instituting an ECMO program for
adults, healthcare systems should carefully evaluate the comparative
effectiveness of ECMO compared with conventional treatments.

Study limitations
> Low number of clinical trials compared to the
number of observational studies (1/9);
> Bias inherent to original data from observational
studies could not be eliminated;
> Some articles were not accessible using UP
credentials;
> Lack of data related to indication, complications,

We gratefully thank our Professor Filipa Canário for her endeavor
throughout the whole year, whose help allowed us to complete the task
we have been assigned. Moreover, we feel our acknowledgements should
also be directed to Professor Altamiro Pereira, PhD, whose reviews
provided our work an undeniable level of quality.
