Pulmonary Function Test / Spirometry
- COPD is particularly characterized if a ratio of forced expiratory volume over 1 second (FEV1) to forced vital capacity (FVC) being < 0.7 and the FEV1 < 70% of the predicted value when compared with a matched control. [1], [2] (see Spirometry).
- Normally, at least 70% of the FVC comes out in the first second (i.e. the FEV1/FVC ratio is >70%). A ratio less than normal defines the patient as having COPD.
- More specifically, the diagnosis of COPD is made when the FEV1/FVC ratio is <70%.
- The GOLD criteria also require that values are after bronchodilator medication has been given to make the diagnosis,
- The NICE criteria also require FEV1%.
- According to the ERS criteria, it is FEV1% predicted that defines when a patient has COPD, that is, when FEV1% predicted is < 88% for men, or < 89% for women.
- Spirometry can help to determine the severity of COPD.[3]
- The FEV1 (measured after bronchodilator medication) is expressed as a percentage of a predicted "normal" value based on a person's age, gender, height and weight:
- The severity of COPD also depends on the severity of dyspnea and exercise limitation. These and other factors can be combined with spirometry results to obtain a COPD severity score that takes multiple dimensions of the disease into account.[4]
