From: Detection of ‘best’ positive end-expiratory pressure derived from electrical impedance tomography parameters during a decremental positive end-expiratory pressure trial

Figure 2

Different electrical impedance tomography (EIT) modalities calculated for the decremental positive end-expiratory pressure (PEEP) trial. Effects of different PEEP levels on regional changes in (A) tidal impedance variation (TIV); (B) regional compliance; (C) ventilation surface area (VSA); (D) center of ventilation (COV); (E) regional ventilation delay (RVD) index; and (F) global inhomogeneity (GI) index. Data are presented as means ± 95% CI. Dashed lines represent the interpolation lines; open circles = non-dependent regions; solid circles = dependent regions; solid squares = entire EIT image.
