Summary

This study tests whether the PulsePoint app can increase the number of people who receive CPR or a defibrillator from bystanders before paramedics arrive. About 340 adults who suffer sudden cardiac arrest in public places will be included. Half of the 911 calls will trigger the app to alert nearby trained volunteers, while the other half will follow standard emergency procedures.
