Résumé
Coronavirus disease 2019 (Covid-19), a severe acute respiratory syndrome caused by coronavirus 2 (Sars-CoV-2), has now spread to all continents. About 5-10 % of Covid-19 patients require intensive care unit admission and mechanical ventilation. Critically ill Covid-19 patients are prone to develop hypoxia, excessive inflammation and frequent thrombotic manifestations affecting both the macrocirculation and the microcirculation.
