Figure 4From: Sustained inflation and incremental mean airway pressure trial during conventional and high-frequency oscillatory ventilation in a large porcine model of acute respiratory distress syndrome Partial pressure of arterial carbon dioxide(PaCO 2 ). PaCO2 (mean ± SD) during recruitment manoeuvre. PCV = pressure controlled ventilation; HFOV = High-frequency oscillatory ventilation. * p < 0.01 vs. TAli; + p < 0.01 HFOV vs. PCV. (n = 9 until 75 min).Back to article page
