the
results.
Interpretation will be displayed if the height, date of
birth and population group are entered for the
subject. There also needs to be a measured value

2. Press the
COPD Risk
button to view the COPD
risk. This calculates a subject’s risk of developing
COPD within the next 10 years, and also the risk if
the subject stopped smoking.
COPD risk will be displayed if the date of birth,
gender and current smoking information has been
entered. There also needs to be a measured value
of FEV1.
3. Press the
COPD Number
button to view the COPD
score.
The COPD number is the measured FEV1 as a
percent of the value compared with a reference
population of people without lung disease. This is
used as a method of categorising the severity of
airway obstruction in subjects with COPD. Most
lung damage is permanent, so the initial COPD
number is unlikely to improve. However, if it
remains close to constant, it is a positive sign that
the subject’s lungs are not suffering further
deterioration. The number will be displayed if the
date of birth, height and population group have
been entered and the COPD check box has been
selected for the subject.
