When you go into cardiac arrest, you've got about ten minutes to live if you don't receive medical attention, and the average emergency response time is seven minutes after you dial 911. In an effort to get folks help more quickly and leverage the iPhone's life saving abilities, the San Ramon Valley Fire Protection District in California has created the FireDepartment app to enlist the help of the citizenry in fighting the (unfortunate) results of a lifetime of eating tacos. The iPhone app -- Android and BlackBerry versions are currently in the works -- allows emergency dispatchers to notify users via text of a nearby crisis. For those feeling heroic, the app displays a map with the victim's location and any nearby automatic electronic defibrillators, and provides "resuscitation reminders" in case you're the CPR teddy-toting type. For now, the service only works in San Ramon but there are plans to port it for use elsewhere. That means we can look forward to a nation of amateur EMTs, which makes us thankful that mouth-to-mouth is no longer a part of CPR. Check the video after the break to see the app in action.
