Doug Woods, a very clever paramedic in Missouri, has put together CPR training with the concept of Guitar Hero. This mash-up (yes, that was meant to be funny) allows CPR students to see in real-time on a computer screen the effectiveness of their compressions on the mannequin. The depth and frequency of the compressions are measured and colored bars appear on the screen to give instant feedback for adjustments. Woods hopes that the interactive mannequin system, paired with an online presentation and test that he developed will allow for shorter, cheaper CPR training, leading to more people being certified.
