Study of Spirometry Finding in Snorers

Abstract

INTRODUCTION Spirometry is indicated to detect whether a pulmonary dysfunction is present or not, to rate the severity of a known pulmonary disease, to follow up the pulmonary function. Snoring is the vibration of respiratory structures and the resulting sound. Snoring during sleep may be the first sign of obstructive sleep apnoea (OSA). Common signs of OSA include unexplained daytime sleepiness, restless sleep, and loud snoring (with periods of silence followed by gasps). With this high prevalence of OSA and the rising worldwide increase in morbidity and mortality in chronic obstructive pulmonary disease (COPD), more research required comparing nocturnal respiratory disturbances with attention directed on the effect of body composition, severity of OSA and severity of airway obstruction. MATERIAL & METHODS A cross-sectional observational study was carried out in snorers at Department of Respiratory Medicine. All patients underwent spirometry and PSG. RESULTS There was no significant correlation between severity of snoring and any spirometry parameter. CONCLUSION In our study, there was no correlation between snoring and spirometry nor between spirometry and AHI. It may be because of less number of subjects in our study, so study with large numbers of subjects are required to bring out the correlation.
