Phone app alerts did not increase bystander CPR rates in study of two major population areas

AI Summary

A preliminary study found that a smartphone app alerting nearby CPR-trained volunteers did not improve bystander CPR or AED response times compared with the standard 911 response. The findings were presented at the American Heart Association's Resuscitation Science Symposium 2026 in Chicago.

A smartphone app designed to alert nearby CPR-trained volunteers resulted in similar response times for bystander CPR or automated external defibrillator (AED) use compared with the standard 911 response for people experiencing cardiac arrest, according to new, preliminary, independent late-breaking science presented Saturday at the American Heart Association's Resuscitation Science Symposium 2026 in Chicago.
