Pulmonary Function Testing Cases

The following cases are designed to help you learn how to interpret pulmonary function tests. Each case contains a short clinical scenario and the pulmonary function tests for that patient. For each case, you should attempt to

  • describe the pattern of abnormality, if one is present,
  • grade the severity of the abnormality and
  • generate a differential diagnosis for the observed abnormality.

The cases have been provided by Kenneth Steinberg, MD, Division of Pulmonary and Critical Care Medicine.
