Figure 3

Trend of mean values of arterial blood gases. Values shown for before (pre-MV), after two hours (2 h-MV) and at the end of mechanical ventilation (end-MV) in the noninvasive positive pressure ventilation (NPPV) (Rectangles; pre-MV: n.15; 2 h-MV: n.15; end-MV: n.11) and the conventional mechanical ventilation (CMV) group (circles; pre-MV: n.15; 2 h-MV: n.15; end-MV: n.8). Dashed lines depicted the individuals values of pH, partial pressure of arterial oxygen (PaO2)/fraction of inspired oxygen (FiO2), partial pressure of arterial carbon dioxide (PaCO2) of NPPV-treated patients. * P < 0.05 between the groups.
