Figures & data

Figure 1 Flow chart synthesizing the clinical pathways of the COVID-19 patients, the respiratory support provided at each step of their hospital stay, and their 60-day mortality. Percentages refer to the previous level in the flow chart, unless otherwise indicated. *With respect to total hospital admissions.

Abbreviations: CPAP, continuous positive airway pressure; NIV, non-invasive ventilation; IMV, invasive mechanical ventilation; ED, emergency department.
