Figure 5From: Electrical impedance tomography measured at two thoracic levels can visualize the ventilation distribution changes at the bedside during a decremental positive end-expiratory lung pressure trialEnd-expiratory lung volume (EELV) calculated from end-expiratory impedance changes. Values are relative to baseline 5 cm H2O positive end-expiratory pressure (PEEP), which was set at 0.Back to article page
