Advanced Pulmonary and Cardiac Support of COVID-19 Patients: Emerging Recommendations From ASAIO-a Living Working Document.

The severe acute respiratory syndrome-CoV-2 is an emerging viral pathogen responsible for the global coronavirus disease 2019 pandemic resulting in significant human morbidity and mortality. Based on preliminary clinical reports, hypoxic respiratory failure complicated by acute respiratory distress syndrome is the leading cause of death. Further, septic shock, late-onset cardiac dysfunction, and multiorgan system failure are also described as contributors to overall mortality. Although extracorporeal membrane oxygenation and other modalities of mechanical cardiopulmonary support are increasingly being utilized in the treatment of respiratory and circulatory failure refractory to conventional management, their role and efficacy as support modalities in the present pandemic are unclear. We review the rapidly changing epidemiology, pathophysiology, emerging therapy, and clinical outcomes of coronavirus disease 2019; and based on these data and previous experience with artificial cardiopulmonary support strategies, particularly in the setting of infectious diseases, provide consensus recommendations from American Society for Artificial Internal Organs. Of note, this is a living document, which will be updated periodically, as additional information and understanding emerges.

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.
