This is an unblinded pilot study to investigate the technical feasibility of using an electrical impedance tomography device for noninvasive pulmonary function monitoring in ALS patients.
For both Cohort I and II, subject participation will require two visits (initial and 3-4 month follow up), which are expected to last approximately 30 minutes. Subjects will undergo EIT imaging with the investigational device prior to and while performing a standard PFT procedure. The actual EIT imaging will last for 10 to 15 minutes.
