[Comparative study of maximal midexpiratory flow rate in normal smoking and non-smoking subjects]. / Studio comparativo del MMF in soggetti normali fumatori e non fumatori.

ABSTRACT

MMF is considered one of the most sensitive parameter to point out initial decay of small airways that should appear prematurely in smokers as compared with non smokers. To verify the above we tested male subjects apparently free from any respiratory disease. They were classed into two groups of equal number the first group of smokers, the second one of non smokers. We did not find any statistically significant difference between the two groups this is probably due to the young age of the subjects and consequently to the relative short period of exposure to tobacco smoke.
