PM 2.5

Individualized alarming particulate matter 2.5 (PM 2.5) wearable device on exacerbations of chronic obstructive pulmonary disease (COPD) patients.

COPD is the third most fatal non-communicable diseases (NCD) worldwide. SDG 2030 set the goal of at least one-third of mortality-due-to-NCD reduction. Exacerbations are the leading causes of hospitalization and death in COPD patients. Previously observation studies found that air pollution particulate matters causes acute exacerbation in these patients. To date, there exists no wearable alarming device to be used by sensitive population and no study has evaluated the efficacy of the PM2.5 detector devices on COPD exacerbations and mortality rates.

This project aims to produce a wearable device and to analyze its efficacy for the first time on COPD exacerbations. The cost of the device would be lower than similar devices while being wearable. And in the result of the utilization of the device, admission rates of COPD patient would be decreased, therefore, the cost of health systems and patients would fall as well. And finally, the data would be utilized to map the places with high air-pollution for further preventive interventions.

Dust storms, and in result, COPD exacerbations are a problem of middle east countries. Additionally, it was observed that the COPD-attributable mortality has increased during recent years; females and males have shown similar patterns which decreases the probability of smoking to be the only cause of deaths. (5) The low-cost of the device, the wearability, and accurate detector will make an appropriate device for mass production and utilizing in all COPD patients. The cost would be less than similar previously produced devices, while the size and ease of use would be more appropriate.



Project aims:

  • To design an alarming pm2.5 wearable device that records PM2.5 and alarms when reaches the cut-point with lower cost comparing to previous detectors
  • To assess the efficacy of alarming PM2.5 wearable device on the frequency and severity of COPD exacerbations and 1-year all-cause mortality
  • To assess the efficacy of alarming PM2.5 wearable device on symptom scores and quality of life in COPD patients
  • To introduce a predictive model of COPD exacerbation
