Abstract

COPD is the most frequent chronic lung disease in all over the countries. Usually COPD is diagnosed late in its natural course, when more than half of the patient's ventilatory reserves are irreversible lost.
The aim of the study was early detection of COPD in mass spirometry.
The spirometry was performed in 180 small towns and villages. Spirometry was done by using mobile laboratory of pulmonary function tests named [dsquote]SPIROBUS[dsquote] equiped in Lungtest 1000 MES, Poland In 2000-2001 - 8557 tests was done. All of the subjects have a good psychophysical status. Group consisted of 46,5% men and 53,5% women with mean age 51,2±]15. Forty one percent of the subjects were smokers with a smoking history 21,17±]16,5 pack-years
Airflow limitation were found in 21% of all studied subjects (14,7% nonsmokers and 28% smokers). In the group of non-smokers mild obstruction was found in 7,4%; moderate obstruction was found 4,4%, and severe obstruction was found in 2,9%. In the group of smokers mild obstruction was found in 14%, moderate obstruction was found 9%, and severe obstruction was found in 5%. The airflow obstruction was directly related to age and smoking habit. In non smokers group below 40 yrs airflow obstruction was observed at 10% and above 40 yrs was adequate 17.7%. Comparing to 13.7% in the group below 40 yrs and 31% in group above 40 yrs in smokers group.
Conclusion: Our study suggests that one third of smokers aged above forty years old have a spirometric signs of COPD.
