From: Physiological response to prone positioning in intubated adults with COVID-19 acute respiratory distress syndrome: a retrospective study

Fig. 2

Variations in PaO2/FiO2, FiO2, Aa gradient, CRS, VR and VD/VT HB for all sessions (A) and first session (B) before (pre PP) and at the end (end-PP) of the prone position session. PaO2: arterial partial pressure of oxygen, FiO2: fraction of inspired oxygen, Aa gradient: alveolo-arterial gradient, VR: ventilatory ratio, VD/VT HB: dead space fraction estimated using the unadjusted Harris-Benedict estimate of resting energy expenditure and the rearranged Weir equation for CO2 production, CRS: Compliance of the respiratory system
