From: Bedside measurement of changes in lung impedance to monitor alveolar ventilation in dependent and non-dependent parts by electrical impedance tomography during a positive end-expiratory pressure trial in mechanically ventilated intensive care unit patients

Figure 5

Response to decremental PEEP steps on tidal impedance change in patients with or without lung disorders. During pressure-controlled ventilation with constant driving pressure, the tidal impedance change per pixel can be regarded as regional compliance change per pixel. The percentage positive of the total Δtidal impedance is calculated from the total increase and total decrease in each Δfunctional EIT image. Data are presented as median and interquartile range.
