Severe acute hypercapnia is independently associated with increased adverse effects and intensive care unit mortality in mechanically ventilated patients. During the severe acute respiratory syndrome coronavirus 2 (COVID-19) pandemic, some patients were placed on extracorporeal carbon dioxide removal support when extracorporeal membrane oxygenation (ECMO) support was at capacity or not offered. We present a patient with severe acute respiratory distress syndrome caused by COVID-19 pneumonia, who was supported with Hemolung Respiratory Assist System (ALung Technologies, Inc., LivaNova, Pittsburgh, PA) via the right subclavian vein as a bridge to lung transplantation after venovenous ECMO support. The patient survived and was discharged home.
