Doing CPR on someone is often not that effective. One reason is that it’s quite hard to know how hard to pump the chest.
Today’s invention is a simple clip-on device to be worn on the outside of clothing and with a pad set to click when squeezed with the correct force (set for an individual -depending on chest size and clothing density). This would be attached on the best spot for CPR and with an instruction to press hard enough to hear clicks, and to the beat of the Bee Gee’s “Stayin’ Alive”).
If the wearer is found lying unconscious, anyone could press on their chest with the correct force to hear the clicks.
