During the study period, we identified 100 pregnant patients with SARS-CoV-2 infection. Mechanical ventilation was required in 8 of these patients. In three cases, proning was performed during the antepartum period. The gestational age ranged from 25 and 30 completed weeks of gestation. We briefly described their clinical course below. For each case, a graphical ( Figures 1 and Figure S1-S3) and numerical (Tables S) representation of the ventilatory parameters in relationship with proning timing is available as supplementary material.
