To introduce the challenge
presented by dyspnea, consider the following vignette and answer
the questions that follow:
A 65 year old man
with emphysema goes to his doctor complaining of an inability
to walk more than a block or two. Three years ago he gave up playing
golf, and one year ago he moved from his house, which had stairs,
to an apartment in a building with an elevator. His daughter now
does the shopping for him.
Question
1.1
The doctor assumes
that the patient's limitation is due to shortness of breath and
that the symptom is due to his emphysema. Do you agree?
