Well for the presentation I found it to be very helpful in feedback, i now know where I want to go in my concepts as well as knowing what I could have done better. My concepts to date were kind of focused on compressions really, but not only compressions but using a piston motion which I used in nearly every concept. So what I am going to do now is take a step back and look at the other aspects as well as compressions. So, I have broken down my concept generation into four sections; Compressions, Respiratory (Airway and Breathing) Defibrillation and Coaching. With my compressions section I want to look at different mechanisms as well as different ways of providing them, getting away from the piston. With respiratory I believe there can be a lot of scope in looking at how i can simulate the head tilt-chin lift manoeuvre as well as providing the rescue breaths. In defibrillation I am still looking into how I can incorporate the AED function. And, finally the coaching area I want to achieve a concept that will talk you through the process of CPR and achieving a training aspect as well.
