Ambulance Victoria are asking people in the GV to sign up to the Good Samaritan App to assist emergency services when a person falls into cardiac arrest.
As the ambulance is on its way the first minutes are critical to keeping someone alive.
The app alerts those close by who have signed up to the app that a person close by is suffering cardiac arrest and alerts them to their location so they can assist with CPR until the paramedics arrive.
With 12,500 subscribed Ambulance Victoria are conducting a campaign to sign up a further 5000 during February.
