Fig. 4From: Experimental blunt chest trauma – cardiorespiratory effects of different mechanical ventilation strategies with high positive end-expiratory pressure: a randomized controlled studyLung mechanics. Changes of inflating pressure (Phigh), total positive end-expiratory pressure (PEEPtot), tidal volume (VT), minute ventilation (MV) for the high frequency inverse ration pressure controlled ventilation (HFPPV) and low tidal volume high PEEP ventilation (HP-CMV) groups. Data are shown as mean and standard deviation. For General Linear Model (GLM) analysis of group effects logarithmic transformation of minute ventilation was used. ns: not significant (P > 0.05)Back to article page
