Prolonged VV ECMO (265 Days) for ARDS without technical complications.

The usual duration of extracorporeal membrane oxygenation (ECMO) in patients with severe acute respiratory distress syndrome is 7-10 days. Prolonged duration ECMO (defined as greater than 14 days) is increasingly being documented with native lung recovery or as a bridge to lung transplantation. We report a case of prolonged duration ECMO (6,364 hours, 265 days) requiring no complete circuit exchange. As critical care improves, prolonged ECMO will continue to pose unique technological and ethical challenges that test our expectations of this treatment modality. There is a critical need for diagnostic modalities to provide objective assessment of native lung recovery in patients requiring prolonged duration ECMO.
