Pulmonary function evaluations benefit many types of patients. Pulmonary disease may frequently be detected by testing years before the onset of signs or symptoms. The early detection of pulmonary disease can be a strong influence in a patient's decision to quit smoking, which reduces the risk of both cardiovascular disease and worsening pulmonary disease. Comparing tests helps the physician determine whether a specific therapeutic regimen is beneficial. Shortness of breath is a common complaint among patients, and pulmonary function tests can help differentiate between cardiac and pulmonary causes. Pulmonary function tests that are performed before a planned surgery help reduce the incidence of postoperative pulmonary complications by identifying patients at increased risk. Finally, patients who report that their ability to work is limited by shortness of breath can be objectively evaluated with pulmonary function tests; the results are sometimes used to document disability in insurance claims.

It is not uncommon to see previous pulmonary function tests recorded in the medical records of patients who are admitted to hospitals. A quick review of those test results may be instrumental in making decisions about current treatment. This course describes the traditional lung function tests - spirometry, lung volumes and capacities; as well as special tests to measure peak flow, lung diffusion, and bronchodilator responses - that respiratory therapists should be familiar with, even if they do not work in a pulmonary function laboratory. In addition, a brief discussion of what may cause abnormal test results is included.

Course Objectives

  • Describe spirometry, the equipment used in spirometry, and spirometry tests and results.
  • Summarize the special procedures used in pulmonary function testing and when they are used.
  • Describe miscellaneous pulmonary mechanics.
  • Draw a normal flow volume loop.
  • Explain how pulmonary function test results are used to identify obstructive and restrictive patterns, and to name the GOLD classifications.
