Acute cardiac care & resuscitation
Impact of smartphone activated first responders on provision of bystander CPR, bystander AED and outcomes for out-of-hospital cardiac arrest (OHCA)
Authors' conclusion
We found that the implementation of technology-activated first responders was associated with an improvement in the performance of bystander CPR, bystander AED application, and OHCA outcomes in an urban area. Further efforts should be made to promote the use of activated first responders in EMS systems.
