A Study of Pulmonary Function Test in Asymptomatic Smokers
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2018, Vol 6, Issue 3
Abstract
Abstract: Smoking is a pernicious scourge of the world today. Smoking is well known to increase the risk of the risk of pulmonary diseases by affecting the pulmonary functions. Hence, emphasis should emphasis should be paid on preventive strategies of these disorders. Our study was to evaluate the effect of smoking on lung functions in asymptomatic smokers. A total of 100 subjects were included which were equally divided in to two groups i.e. of smokers and non - smokers. The lung functions tests were carried out on each subject in both the groups. No statistically significant difference was seen in the baseline characteristics of the two groups. There was no statistically significant difference between the two groups regarding mean values of blood pressure and heart rate, through; values were higher in smokers as compared to non-smokers. All spirometric values in two groups had statistically high difference and were higher in non-smokers as compared to smokers. FEF25-75% was the n he most sensitive indicators for the detection of early airway obstruction. There was progressive s progressive deterioration in all the four spirometric parameters with increasing pack years of smoking. Although the smokers were young and asymptomatic, still the spirometric were significantly deranged as compared to controls. Even smokers with history of less pack years of smoking also had significant abnormalities of lung function. All spirometric parameters deteriorated significantly with increasing 3 pack years of smoking. FEF 25-75% seems to be the most sensitive parameter in detecting early airway obstruction. In view of the above finding, smoking should be strongly discouraged at the early asymptomatic stage to prevent any further lung damage.
