From: PaCO2 and alveolar dead space are more relevant than PaO2/FiO2 ratio in monitoring the respiratory response to prone position in ARDS patients: a physiological study

Figure 1

Alterations during PP in PaO 2 /FiO 2 , PaCO 2 , plateau pressure (Pplat) and alveolar dead space (VD alv /V T ) in responders (solid lines) and nonresponders (dotted lines) according to PaO 2 /FiO 2 changes. "PaO2 responders" were defined by an increase in PaO2/FiO2 > 20 mmHg after 15 hours of PP (PP H15). Shown are box and whisker plots. Median = horizontal line inside the box; upper and lower quartiles = whisker plot. Boxes and triangles represent values higher or lower than the upper or lower quartiles. *P < 0.05 for comparison of changes in responders versus nonresponders. PP: prone position.
