A new app to alert CPR-trained bystanders when someone is suffering a cardiac arrest is about to start saving lives in New Zealand.
The app, called GoodSAM (Good Smartphone Activated Medics), allows members of the public who are trained in CPR to register as "responders".
When someone is having a cardiac arrest, an alert is sent to nearby responders who may be able to step in and help.
"Cardiac arrest can happen to anyone at any time," said Wellington Free Ambulance medical director Andy Swain.
"In New Zealand, about 2000 people per year are treated for cardiac arrests and only approximately 15 per cent survive. Survival is largely due to the quick actions of bystanders initiating help within the first few minutes. For every minute without CPR or defibrillation, survival decreases by 10 per cent."
