Probability of extracorporeal membrane oxygenation (ECMO) support over time with respect to the primary cause of acute respiratory distress syndrome (ARDS). Kaplan-Meier curves of the probability of continued venovenous ECMO support for patients with COVID-19 infection (COVID-19) (A) versus patients without COVID-19 infection (non-COVID-19) (B) after exclusion of one non-COVID-19 patient who was bridged to lung transplantation for 71 d with awake ECMO. C, Probability for non-COVID-19 ECMO patients with viral pneumonia versus non-COVID-19 ECMO patients with ARDS without viral pneumonia (D) for non-COVID-19 ECMO survivors with influenza versus non-COVID-19 ECMO survivors with community-acquired bacterial pneumonia. Comparisons were performed with the log-rank test.
