When it comes to helping a victim of cardiac arrest, it's all about speed. PulsePoint, a life-saving mobile app, may not necessarily increase the speed at which first responders arrive, but it adds more legs to the race.
Santa Clara County, Calif., agencies began using the PulsePoint app earlier this year with the goal of mobilizing CPR-trained residents and bystanders into becoming first responders.
The free app uses location-based technology to alert CPR-trained citizens if someone in their immediate area is experiencing sudden cardiac arrest. The alerted citizen can then choose to spring into action, find the victim and begin resuscitation until official emergency responders arrive.
