Effect Of Air Quality Index On Peak Expiratory Flow Rate, Spo2 And Minute Ventilation In Non-Smoker Individuals

Abstract

INTRODUCTION: This study explores the effects of ambient air quality as indicated by the air quality index (AQI) ON respiratory function in non- smoker individuals , specifically examining peak expiratory flow rate (PEFR) blood oxygen saturation (SPO2) and minute ventilation . this study involved 100 healthy non – smokers .

METHODS: This study is conducted in Delhi NCR region , a highly polluted area with varying air quality levels , to assess the effects of AQI on respiratory functions in non – smokers . A total of 100 healthy non - smokers  , aged 18-50 years with no history of respiratory disease or other chronic conditions were recruited for the study . The AQI data was obtained from the official air quality monitoring stations in Delhi NCR which were installed and controlled by CPCB.

RESULTS: Respiratory health is greatly impacted by air quality , and the AIR QUALITY INDEX is a vital indicator of air pollution levels. The purpose of this study is to examine how different AQI levels affect respiratory parameters in non- smokers , particularly minute ventilation, oxygen saturation (SPO2), peak expiratory flow rate (PEFR). The study makes the assumption that elevated AQI reading , especially those in the dangerous and unhealthy ranges ,will cause a drop in PEFR, a drop in minute ventilation. This study sheds light on the immediate effects of air pollution on healthy people by carefully monitoring and measuring these indicators.
