Pulmonary Function Tests (PFT)

  • D. John Doyle


Pulmonary function testing is commonly carried out to assess pulmonary status, especially in patients with decreased pulmonary reserve (eg, smokers) as well as in patients for which thoracic surgery is contemplated (eg, pneumonectomy). Such testing provides data such as total lung capacity, vital capacity, residual volume, etc. However, a given set of pulmonary function test (PFT) results must be interpreted in the context of the patient’s age, sex, weight, and height; that is, they must be interpreted relative to normal values for that patient.
