ABSTRACT
COVID-19-induced acute respiratory distress syndrome (ARDS) has challenged medical providers. In severe cases, patients present with poor lung compliance, requiring not only lung protective mechanical ventilation strategies, but also extracorporeal support. Due to the nature of the pandemic, the extracorporeal carbon dioxide removal device called Hemolung Respiratory Assist System became available under the Food and Drug Administration Emergency Use Authorization for patients with COVID-19-induced ARDS. This allowed application of the device to treat patients with recrudescent ARDS following an acute aspiration pneumonia following two previous veno-venous extracorporeal membrane oxidation treatment series, in the setting of hypercapnic respiratory acidosis.
