I've a keen interest in such life-saving devices particularly since an ex-boss died of a heart attack at home right after an evening run and an acquaintance recently suffered fatal cardiac arrest. Could they have been saved? Some say it's all in the hands of fate, but with a gizmo like this, fate could just be thwarted because even someone with no cardiopulmonary resuscitation (CPR) training can administer crucial first aid on the spot.
Unfortunately this is only a concept for now. But designer Ryan Helps, who even has a name to match, has created a device that takes the guesswork out of saving lives. Just place the CPR-Pad on the chest and position your hands as shown in the diagram, and it will display the optimal way to push the chest correctly.
