Fig. 5From: Real-time effects of PEEP and tidal volume on regional ventilation and perfusion in experimental lung injuryRegional distribution of pulmonary perfusion in the control (left, n = 4) and injured (right, n = 6) groups. Both larger PEEP and larger VT determined a significant perfusion change in each of the ROIs considered: nondependent (p = 0.030), middle (p = 0.006), and dependent (p = 0.001). PEEP = positive end-expiratory pressure. VT = tidal volumeBack to article page
