Severe acute respiratory syndrome (SARS-CoV2) due to novel Coronavirus (2019-nCoV) related infection (COVID-19) is characterized by severe ventilation perfusion mismatch leading to refractory hypoxemia. To date, there is no specific treatment available for 2019-nCoV. Nitric oxide is a selective pulmonary vasodilator gas used in as a rescue therapy in refractory hypoxemia due to acute respiratory distress syndrome (ARDS). In-vitro and clinical evidence indicate that inhaled nitric oxide gas (iNO) has also antiviral activity against other strains of coronavirus. The primary aim of this study is to determine whether inhaled NO improves oxygenation in patients with hypoxic SARS-CoV2. This is a multicenter single-blinded randomized controlled trial with 1:1 individual allocation

To date, there is no specific treatment available for 2019-nCoV. Nitric oxide is a selective pulmonary vasodilator gas used as a rescue therapy in refractory hypoxemia due to acute respiratory distress syndrome (ARDS). In has also shown in-vitro and clinical evidence that inhaled nitric oxide gas (iNO) has antiviral activity against other strains of coronavirus.
The primary aim of this study is to determine whether inhaled NO improves oxygenation in patients with hypoxic SARS-CoV2.
This is a multicenter randomized controlled trial with 1:1 individual allocation. Patients will be blinded to the treatment.
Intubated patients admitted to the intensive care unit with confirmed SARS-CoV-2 infection and severe hypoxemia will be randomized to receive inhalation of NO (treatment group) or not (control group). Treatment will be stopped when patients are free from hypoxemia for more than 24 hours.
