Correlation of Carbon Monoxide in the Body With Peak Expiratory Flow Rate and Chest Expansion in Road Side Vendors Near Asarwa Area- An Observational Study.

Background: Prolonged exposure to vehicular emissions, particularly carbon monoxide (CO), poses significant health risks to individuals working in high-traffic environments. Roadside vendors in Asarwa, Ahmedabad, are continuously exposed to such pollutants, potentially compromising their respiratory health. This observational study aims to investigate the correlation Objective: between CO levels in the body and indicators of pulmonary function—Peak Expiratory Flow Rate (PEFR) and chest expansion among roadside vendors in the Asarwa area. Methods: Study was conducted on vendors aged 20-55 years where Exhaled CO levels were measured using a Smokerlyzer, PEFR was assessed via a peak flow meter, and chest expansion was recorded using standard tape. Preliminary findings suggest a negat Results: ive correlation between elevated CO levels and both PEFR and chest expansion, indicating compromised respiratory function. The study Conclusion: highlights the potential impact of environmental CO exposure on pulmonary function highlighting the need for regular respiratory screening and public health interventions to mitigate pollution-related health risks .
