VV-ECMO in severe COVID-19: multidimensional perspectives on the use of a complex treatment
Accurately selecting patients who are likely to benefit from venovenous extracorporeal membrane oxygenation (VV-ECMO) for severe respiratory failure is crucial given its low availability, substantial invasiveness, associated complications, and high financial costs. Existing selection criteria are influenced by multidimensional factors, including local logistics and geographical variation in health-care provision, expert opinion, and data from observational studies and a single randomised controlled trial of ECMO for severe acute respiratory distress syndrome.
