The Covid-19 pandemic led to a major influx of patients suffering from acute hypoxemic respiratory failure, which conducted intensivists to adapt ICU structures and question respiratory support strategies. Available data suggest that pathophysiology of Covid-19 associated - acute respiratory distress syndrome (ARDS) is substantially similar to the pathophysiology of ARDS unrelated to Covid-19. Specific vascular injuries may however be more frequent during Covid-19 and some patients may present a major alteration in hypoxic pulmonary vasoconstriction. To date, ventilatory support strategies of patients with Covid-19 should be in line with guidelines for ARDS unrelated to Covid-19, including in particular a cautious evaluation of positive end-expiratory pressure effects.
