Effects of Particulate Matter on the Pulmonary Function and Acute Exacerbation of COPD and Asthma

Pulmonary Function Clinical Trial

Official title:
Effects of Particulate Matter on the Lung Function and Acute Exacerbation of COPD and Asthma Patients--A Multi-center Cohort Study

Clinical Trial Summary

Particulate matter(PM) exposure has been shown to increase the morbidity and mobility of a variety of respiratory diseases, including COPD and asthma. This study focus on the effects of PM on the pulmonary function and acute exacerbation of COPD and asthma patients in China, where PM exposure is much heavier than the United States and European countries.
