Inclusion Criteria:

- >18 years of age

- Diagnosis of a chronic pulmonary disorder (a diagnosis of lung cancer is not required
as the symptom of dyspnea, not cancer itself, is targeted)

- If diagnosed with lung cancer, must have completed definitive treatment more than 6
months prior

- At least moderate dyspnea defined by a BDI score of 6 or less in the Self-
Administered Computerized Versions of the Baseline and Transition Dyspnea
Indexes(SAC-BDI/TDI)13,14 (This cutoff score is close to the score of 5.7 used to
define "moderate dyspnea" in the publication that validated the instrument and is
selected by attending physicians in the Pulmonary Service as a good indication of
"moderate dyspnea" in clinical practice. A typical person with BDI of 6, for example,
would be a 52 year old woman who has to pause when walking because of dyspnea and/or
has eliminated doing an activity because of dyspnea).

- Able to safely complete the Six Minute Walk Test (6MWT)15 as per attending
physician's clinical judgment.

stable for the next 3 months as determined by project PIs and other Pulmonary
Medicine faculty.

Exclusion Criteria:

other means (e.g. pleural effusion, pulmonary embolism, acute infection, anemia
