Functional assessment of chronic obstructive pulmonary disease.

PURPOSE

To describe available methods for assessing functional capacity in persons with chronic obstructive pulmonary disease (COPD).

DATA SOURCES

An extensive literature review is used to provide pertinent information.

CONCLUSIONS

COPD disease affects millions of Americans and is physically and psychologically distressing. The hallmark of chronic obstructive pulmonary disease is irreversible airflow limitation and dyspnea. Dyspnea is a major contributor to decreased exercise capacity and functional status in this population. Understanding the methods to complete a functional assessment is important for all practitioners caring for this population.

IMPLICATIONS FOR PRACTICE

This paper provides an overview of current methods used to assess functional status, including pulmonary function testing, exercise testing, and anthropomorphic and self-report measurements. In addition, there is discussion of the indications and contraindications for exercise testing in chronic obstructive pulmonary disease and the clinical significance of performing a global composite of functional ability.
