Although there's usually one super prepared or designated individual that knows CPR, the majority of people probably don't have the proper training to assist in a medical emergency—however, the Cardio First Angel is a handy heart attack help device that will guide you through the process of saving a life. Even if you're not trained in CPR, Cardio First Angel is designed to be highly user-friendly and not cause any injury to someone who already needs aid.
The device is like a big red button that can be placed on someone's chest and compressed with both hands, just as you would normally with CPR. These instructions are clearly printed in pictures on the device as a quick reference guide. At the right pace, the device emits clicking sounds so that you can be sure that the CPR is being performed correctly.
