Flowchart for non-invasive ventilation support in COVID-19 patients from a northern Italy Emergency Department

With the rapid pandemic spread of the novel coronavirus (SARS-CoV2), Emergency Departments of affected countries are facing an increasing number of patients presenting with hypoxemic respiratory failure due to coronavirus disease 2019 (COVID-19). Providing mechanical support and endotracheal intubation can be challenging due to a number of patients larger than usual, often exceeding available resources. Considering the lack of recommendations available, we developed a flowchart to standardize the first approach to patients presenting to the Emergency Department with hypoxemic respiratory failure due to COVID-19.
