Extracorporeal membrane oxygenation in adult acute respiratory distress syndrome.

The role of extracorporeal membrane oxygenation (ECMO) in supporting adult refractory respiratory failure continues to evolve. Technical advances and the clinical challenges of H1N1 associated severe ARDS have spurred a resurgence of interest in ECMO. Published systematic review and pooled analyses point out the limitations of available studies, however, a growing body of evidence suggest potential for benefit. Referral to a specialized center with ECMO experience should be considered early after the initiation of high-level ventilator support in adult patients with severe ARDS.
