Purpose: The purpose of this study was to provide basic data for improving the response capacity of 119 EMS systems by analyzing the effects of particulate matter on cardio-cerebrovascular and respiratory symptoms in the pre-hospital stage. Methods: We examined 46,389 patients who transferred to the hospital with complaints of cardiopulmonary arrest and cardio-cerebrovascular and respiratory symptoms by 119 ambulances in Incheon from 2016 to 2018. Results: The probability of 119 emergency dispatch for patients with cardiopulmonary arrest increased 2.8-4.0% from the day of symptom onset until two days before hospital presentation as particulate matter 10μm or less in diameter(PM10) increased by 10μg/m3 (OR=1.028; 95% CI=1.014–1.041, p=0.000, lag 0), (OR=1.040; 95% CI=1.024–1.056, p=0.000, lag 1), (OR=1.032; 95% CI=1.016–1.049, p=0.000, lag 2). Meanwhile, emergency dispatch increased 3.6-6.1% for PM2.5 in creased by 10μg/m3 (OR=1.046; 95% CI=1.024–1.068, p=0.000, lag 0), (OR=1.061; 95% CI=1.035– 1.088, p=.000, lag 1), and (OR=1.036; 95% CI=1.010–1.063, p=0.006, lag 2). Conclusion: Emergency medical technicians (EMTs) who respond to 119 calls should rapidly and accurately evaluate patients and provide professional emergency care by identifying the characteristics of the vulnerable groups relative to particulate matter size. To prevent the occurrence and exacerbation of symptoms caused by particulate matter, EMTs should be prepared and equipped with a response system for high particulate matter in the EMS system.
