(CBS) — Naperville has become the first Chicago area community to connect with a smart phone app that gives people trained in CPR or defibrillator use a way to put that knowledge to use.

“Naperville is not afraid to lead. We as a community are dedicated to innovation,” said Naperville Mayor Steve Chirico, talking about the city’s adoption of the Pulse Point Respond app.

Fire Chief Mark Puknaitis said: “Pulse Point Respond is an app that notifies registered users who are certified in CPR and AED use of a cardiac emergency within a 12-block radius of their current location.”

Chief Puknaitis says it’s hoped those who can help administer aid before fire units get there do so.

Time is critical.

The American Heart Association says for every minute that passes without CPR or defibrillation, the chances of patient survival decrease 7 percent to 10 percent.

The fire chief says Naperville spent $20,000 to set up a link between its 911 dispatch center and the Pulse Point Respond app. He says it’ll cost about $4,000 a year to maintain, which he says is worth it.
