In a study showcased at the American Heart Association’s Scientific Sessions 2015 in US, a new smartphone app developed by Japanese researchers from Kyoto University was in the limelight as it alerted rescuers with life-saving AED when an outside-of-hospital cardiac arrest occurs nearby. People, who were earlier restricted to being just bystanders, may now deliver shocks using an automated external defibrillator (AED) to people who have cardiac arrest outside hospital to better their chance of survival.

Called AED-SOS, the new smartphone application signals potential rescuers when a cardiac-arrest outside-of-hospital situation arises. Rescuers may then act upon receiving the notification and deliver the much-required AEDs to the scene.

Researchers observed whether the application can shorten the process of finding and delivering AEDs by studying two sets of patients – one who were assigned to a group using the AED-SOS app and the other assigned to a group without the app. Both groups were made to participate in scenarios featuring mock out-of-hospital cardiac arrest.

Researchers deduced that among the 52 people under their study, recognition of the out-of-hospital cardiac arrest to AED delivery was an average 133.6 seconds in the AED-SOS group, while it was 202.2 seconds in the group without the app. By shortening this time for bystanders to recognise a cardiac arrest and deliver shocks via AEDs, researchers believe they may be able to increase the chances of the patient’s survival.
