The End-expiratory trend view or ΔEELI-trend view is used to monitor
regional changes of End Expiratory Lung Impedance (∆EELI). ∆EELI is
strongly correlated with changes in End Expiratory Lung Volume (∆EELV).
The ∆EELI trend is useful to asses changes in lung volume for example after
changing the PEEP and after recruitment maneuvers for the re-opening of dorsal
atelectases as well as for the detection of de-recruitment of individual lung areas.

Ref and C can be positioned along the time axis. Changes can be seen in
the ∆EELI differential image. Areas in orange show a regional decrease
(e.g. caused by de-recruitment), areas in light blue a regional increase in
EELV (e.g. caused by recruitment).
In the above example, a ∆EELI value of -0.62 x TVglobal Ref means a
decrease in end-expiratory lung impedance or EELV by the amount of
global tidal variation at Ref , i.e. 0.62 x Vt at location Ref (in this
example, this would be 0.62 x 447 ml). The regional impedance curves
show regional changes and the numerical values.
