Figure 3From: The EIT-based global inhomogeneity index is highly correlated with regional lung opening in patients with acute respiratory distress syndromeComparison of GI index values and respiratory system elastance. The values of respiratory system elastance (Ers) are indicated with red circles. The GI index values with (blue solid line) and without (blue dashed line) low-pass filtering of cardiac related signals are plotted. Periodic cardiac activities can be recognized. The same patient as in Figure 1 is shown.Back to article page
