Air pollution and activation of mobile medical team for out-of-hospital cardiac arrest.

Background: The association between air pollution exposure and cardiovascular events is well established, and the effect of short-term exposure on out-of-hospital cardiac arrest (OHCA) has received some attention. The effect of air pollution exposure and the activation of mobile intensive care units (MICUs) for cardiac arrest have never been studied.

Objective: We analyzed associations between air pollutants and MICU activation for OHCA.
