As electrical impedance tomography measures variation of impedance values, a reference is needed to express the magnitude of the changes. The end-expiratory lung impedance variation (ΔEELI) of each respiratory cycle is expressed as a function of the tidal variation of the first stable respiratory cycle (VT global C1) of the first phase.

Global end-expiratory lung impedance variation (ΔEELI) in the supine and prone positions while breathing ambient air (phases 1 and 3) versus on high-flow nasal cannula (phase 2). ΔEELI is higher during the ambient air phases.

Regional end-expiratory lung impedance variation (ΔEELI) in the supine position. Regional ΔEELI is higher in the ventral regions (1 and 2).
- Fig. 4.
Image, curves, and numbers of global and regional end-expiratory lung impedance variation (ΔEELI) of a subject breathing in supine position. There is a substantial difference between the ventral (1 and 2) and dorsal (3 and 4) lung regions.

Regional end-expiratory lung impedance variation (ΔEELI) in the prone position. Note the more homogeneous ΔEELI distribution.
