Figure 1

Example of electrical impedance tomography (EIT) image reconstruction. Shown is the distribution of impedance to the dependent and non-dependent lung regions of one representative patient. The lighter the color, the higher the impedance and the more aerated the lung region. The surface area used in all calculations at every positive end-expiratory pressure (PEEP) step is equal to the largest surface area. The EIT image is divided into two equal regions of interest represented by the white line; all EIT modalities are calculated using this setup. Decreasing the PEEP value resulted in a decrease in aeration of the lungs, especially in the dependent region.
