Genesis Electrical Impedance Tomography (EIT): A Preliminary Study

The purpose of this study is to evaluate EIT for use in pediatric respiratory disease populations including neuromuscular and bronchopulmonary dysplasia, as well as in age and height matched controls.

Researchers will use EIT to determine changes in regional ventilation with pulmonary interventions including airway clearance and invasive and noninvasive ventilation in a pediatric respiratory disease population.
