3. 1st National Spirometry Day 31st March 2004
Scientific Objectives :
1. Determine the prevalence of COPD and asthma in a selected group (possibly to be corrected by taking a random sample of the general population).
2. Examine whether PEFR is a valid method for the detection of COPD.

3. Examine to what extent MEFR and FEF75-25 are reduced in patients with COPD and linked to COPD more than to smoking.
