INTRODUCTION Recent studies have shown that using EIT to monitor ventilator
dependent patients appears to have much promise (Frerichs et al. 2006). Its application
allows a possible view of regional ventilation that is dependant on the amount of positive
end expiratory pressure (PEEP). Since EIT is a low resolution imaging modality with
nonlinear characteristics, questions arise as to where in the image and to how large will
be the area of change. Using a model, this study attempts to answer these questions.
This approach would be useful in evaluating various reconstruction algorithms as
suggested by Alder et al 2010.
