To determine, according to the different recommendations, the percentage of smokers having COPD among a population of smokers of more than 40 Packets/Year (PY) addressed for plethysmography. The plethysmographic data of 531 consecutive stable male smokers that underwent reversibility testing (400 µg of Salbutamol®) were analyzed. The mean ± SD of age, cigarettes consumption, PBD FEV1 (%), were, respectively, 61 ± 11 Yr, 64 ± 20 PY and 52 ± 21%. The percentages of subjects having COPD according to the above criteria were 75.5% (SPLF old criterion); 71.2...Continue Reading
