Fig. 5From: Experimental blunt chest trauma – cardiorespiratory effects of different mechanical ventilation strategies with high positive end-expiratory pressure: a randomized controlled studyCT analysis. Effects of high frequency inverse ration pressure controlled ventilation (HFPPV) and low tidal volume high PEEP ventilation (HP-CMV) groups on percentage of: nonaerated lung (%Mnon), poorly aerated lung (%Mpoor), normally aerated lung (%Mnorm), and hyperinflated lung (%Mhyper). All CT-parameters were calculated as percentage of the total mass of tissue present in the single CT-slice. ns: not significant (P > 0.05)Back to article page
