Decremental PEEP trial and EIT measures. Top, global impedance waveform during decremental PEEP trial from 14 cmH2O to 0 cmH2O with decremental steps of 2 cmH2O. At each step, EIT data were analyzed. Mid-top, EIT tidal images corresponding to each PEEP level. Calculated EIT measures are shown with values and images. Mid-bottom and bottom, images depict the center of ventilation (CoV) and overdistension/collapse (ODCL) at each PEEP level. In the ODCL images, blue and white indicate sites affected by overdistension and collapse, respectively. The first value represents overdistension (%) and second value represents collapse (%)
