The PRISMA guidelines were followed throughout the review. A thorough search of the literature was done on Embase, Medline, PubMed Central, and PubMed. We next screened the articles based on our inclusion criteria, and key terms. Results: In this review, we considered eight trials with 3642 patients overall: one cohort study, one randomized controlled trial, and six observational studies. Rates of mortality showed notable variance. A number of variables surfaced as possible predictors of the outcomes, including the age of the patient, the level of hypoxemia, the degree of mechanical ventilation, comorbidities, and ECMOrelated variables.
Many factors, particularly those connected to the patient, such as age, the degree of hypoxemia, and the cause of ARDS, can explain the heterogeneity of outcomes. Mortality rates are also influenced by ECMO-related issues, such as bleeding from anticoagulation, the development of thrombocytopenia, and cannula-related problems.
