Comparative Study of Peak Expiratory Flow Rate in Smokers and Non Smokers
Journal Title: International Journal of Medical and Health Sciences - Year 2014, Vol 3, Issue 2
Abstract
Introduction: Peak expiratory flow rate (PEFR) is a simple index of pulmonary function and can be used in researches, clinical practices and even under field conditions to assess status of large airways. Objectives: The current study was undertaken to compare PEFR in smokers and non smokers, to know the effect of duration of smoking and type of smoking on respiratory tract. Materials and Methods: Study was conducted on 60 healthy male smokers and 60 healthy male non smokers. PEFR recording was done using Wright’s peak flow meter. Statistical analysis was done using unpaired t- test and ANOVA tests. Results: The mean PEFR increased up to the age of 40 years and then gradually decreased after 40 years in both smokers and non smokers. Mean PEFR values were significantly lower in smokers than non smokers in all age groups. The mean PEFR among smokers ranged from 408 L/min to 532.22 L/min where as from 481.43 L/min to 574.61 L/min in nonsmokers. Mean PEFR values decreased significantly as duration of smoking increased. Conclusions: In conclusion the present study revealed, a significant association between reduction in PEFR with advancing age after 40 years. Tobacco smoking in any form, (beedi, cigarette or both) has significant deleterious effects on respiratory tract. Smokers even if they are symptom free, have lower values of PEFR than non smokers. The diminution of PEFR runs more or less in parallel with the duration of smoking. Beedi smoking affects respiratory tract more adversely than cigarette smoking. Early detection of air flow obstruction and smoking cessation may result in significant health gain.
