Early Usage of Extracorporeal Membrane Oxygenation in the Absence of Invasive Mechanical Ventilation to Treat COVID-19-related Hypoxemic Respiratory Failure.

A subset of patients with coronavirus disease 2019 (COVID-19) develop profound respiratory failure and are treated via invasive mechanical ventilation (IMV). Of these, a smaller subset has severe gas exchange abnormalities that are refractory to maximal levels of IMV support. Extracorporeal membrane oxygenation (ECMO) has been used successfully in these circumstances. However, using ECMO only after failure of IMV exposes patients to the risks of ventilator-induced lung injury. We report a successful outcome using ECMO in the setting of COVID-19 in the absence of IMV failure in an awake, nonintubated patient. This approach may be beneficial for selected patients with COVID-19.
