ACD CPR movement analysis and redesign

In the current first aid skill departments, "Active Compression-Decompression CPR (ACD CPR)" is being discussed amongst a large number of professionals in the area. Both theory analysis and animal tests prove the rise of cardiac output, but the effects haven't been obvious in real life first aid procedures. This study, therefore, is by studying the interrelationship between ACD CPR and the user, to find out the cause that made ACD CPR effects not as obvious as expected, at the same time, pinpoint the problem and give solutions. The study looks at the ACD CPR device form analysis as well as the mechanical design of the kit and come up with solutions for each, at last using motion experiments to test the analysis results and reasonable guesses. Results show that the ACD CPR control panel design directly affects the quality of users' force exertion motions, and the height of the ACD CPR kit caused by mechanical design is another important effect. At the end, through a re-design and motion experiments we prove that the analysis and reasonable guesses of this study were correct, and the new ACD CPR device has truly made an improvement in the holding and griping area.
