Cardiac arrest? There’s an app for that–this one, which alerts citizens who know CPR if someone in the vicinity needs help.

The San Ramon Valley Fire Protection District, not typically known for its high-tech innovations, has nevertheless launched a brilliant iPhone app that could help save lives.
Sales of applications for iPhones, iPads and other mobile devices are forecast to exceed $15bn (€10.9bn) this year.
Downloads of popular games, such as Angry Birds and Doodle Jump, are expected to lead to a near-tripling of global app sales, according to research firm Gartner.
Stephanie Baghdassarian, research director at Gartner, said the big rise in expected sales from $5.2bn in 2010 was due to the popularity of the iPad and other tablet computers.
“Something massive has happened,” she said. “It’s called the iPad, and all of its little brothers and sisters and cousins that are copying Apple.”
Ms Baghdassarian said apps are “by far” the fastest-growing sector of the telecoms and technology industry, and could eventually overtake money generated by phone calls.
