Sudden cardiac arrest? This app can help you

Washington DC: For those experiencing cardiac arrest, there's now an app that can call someone with an AED to the scene.

The new smartphone application helps connect rescuers with lifesaving AEDs and victims with sudden cardiac arrest, according to research presented at the American Heart Association's Scientific Sessions 2015.

Japanese researchers developed the app, called AED-SOS, which signals potential co-rescuers in communities when an out-of-hospital cardiac arrest has occurred and where. Co-rescuers then deliver the needed AEDs to the scene.

Researchers tested whether the app can shorten the process of finding and delivering AEDs by studying participants who were assigned to either an AED-SOS group or a group without the app. Both groups participated in scenarios involving mock out-of-hospital cardiac arrests.

Researchers found that among the 52 people they analyzed, the time from recognition of the out-of-hospital cardiac arrest to AED delivery was an average 133.6 seconds in the AED-SOS group, versus 202.2 seconds in the group without the app.

Shortening the time bystanders recognize out-of-hospital cardiac arrest to when they deliver shocks with AEDs could increase survival, researchers said.
