Figure 2

Advanced respiratory monitoring during the PEEP trial in a porcine ALI model. Illustrated are the changes of paCO2 (A) and PaO2/FiO2 (B) reflecting ventilation and oxygenation, respectively, and dynamic lung compliance, Cdyn (C). Dead space (DS) is presented as fractions of expiratory tidal volume; illustrated are airway DS (D), physiologic DS (E) and alveolar DS (F). Measurement points are before ALI induction at BASELINE, after randomly positioning in either supine or prone position at ALI_SP/PP; at incremental PEEP 10, 20 and 30; and at decremental PEEP 20d and 10d. Full lines represent supine and broken lines prone position. Values are medians and interquartile range (IQR); *significant group differences p < 0.05; **significant group differences p < 0.01.
