Significance of spirometry

Today, a spirometer is the most valuable respiratory diagnostic tool available to health care providers. Spirometry is recommended in the practice guidelines for the diagnosis and management of both asthma and COPD. The FEV1 measurement is so important that it is currently the primary end point in clinical trials for nearly every respiratory drug approved today. Spirometry is also now required for disability evaluations in many countries and in occupational respiratory surveillance and physicals. Today we use spirometry testing to:

Compare lung function with known standards that show how well the lungs should be working
Measure the effect of chronic diseases like asthma, chronic obstructive lung disease (COPD), or cystic fibrosis on lung function
Identify early changes in lung function that might show a need for a change in treatment
Detect narrowing in the airways
Decide if a medicine (such as a bronchodilator) could be helpful to use
Show whether exposure to substances in the home or workplace have harmed the lungs
Determine ability to tolerate surgery and medical procedures. (2)
