Overview

This study plans to learn more about ways to look at participant's lungs using new machines called Electrical Impedance Tomography (EIT). The EIT does not use harmful radiation like CT or x-ray. It is read through electrodes like using EKG reading heartbeats.

The investigators want to compare the results of patients who have chronic respiratory disease to patients without chronic respiratory disease to learn more about lung structure and composition.
