Peak Expiratory Flow Rate In Cigarette Smokers

CO Ukoli, DE Joseph, MA Durosinmi


Objective: To compare lung function between smokers and non-smokers using Peak Expiratory Flow Rate (PEFR).

Methods: This study examines the peak expiratory flow rate (PEFR) of three hundred and forty cigarette smokers, age and sex-matched with PEFR of equal number of non-smokers.

Results: The mean PEFR of all smokers (males and females) was 225.0 + 62.79 L/min. (P<0.05). the PEFR of smokers was found to be significantly lower than that of non-smokers suggesting that the lung function is significantly reduce in smokers. Duration of smoking of 24 months or more was the main factor that affected their PEFR.

Conclusion: Long duration of smoking is associated with significant reduction in lung function. This can be detected with this simple but reliable test of PEFR even in rural clinics.
Key words: Peak Expiratory Flow Rate: Cigarette Smokers.
