Nitric Oxide Ventilation Improves Recirculation and Right Ventricular Function During Veno-Venous Extracorporeal Membrane Oxygenation in a COVID-19 Patient

Patients with coronavirus disease 2019 (COVID-19) are prone to pulmonary artery hypertension (PAH) and right ventricular pressure overload due to severe bilateral infiltrates, high ventilation pressures, persistent hypoxemia, pulmonary fibrosis, and/or pulmonary embolism. In patients on extracorporeal membrane oxygenation (ECMO), this potentially leads to increased recirculation. In the current report, the authors present a case in which continuous inhaled nitric oxide (iNO)-enriched ventilation was effective in terms of PAH and recirculation reduction in a COVID-19 patient on veno-venous ECMO.
