Fig. 2From: Real-time effects of PEEP and tidal volume on regional ventilation and perfusion in experimental lung injuryArterial partial pressure of O2 and fraction of inspired oxygen ratio (PaO2/FIO2; a), mean airway pressure (b), and cardiac output (c) in the control (left, n = 4) and injured (right, n = 6) groups. PEEP = positive end-expiratory pressure. VT = tidal volumeBack to article page
