Physiologic effect of the first prone positioning session and impact on patient outcome. Effect of the first proning session on change in PaO2/FiO2 ratio (a PaO2/FiO2 in after prone position minus PaO2/FiO2 before prone position), change in driving pressure (b driving pressure after prone position minus driving pressure before prone position) and ventilator-free days (c) in responders (blue) and non-responders (grey) patients with acute respiratory distress syndrome related to COVID-19
