공공기관 설치용 자동 제세동기 사용성에 관한 연구

Abstract

Background Sudden cardiac arrest is one of diseases still has a problem what I mentioned above. By the revised bill of the emergency medical service act or the building act, it is rapidly increased and steadily increasing now that the number of institutions which have duty of possession of automated external defibrillators, however, application history of the automated external defibrillators is very low. Therefore, a strategic approach of the design of automated external defibrillators is needed. Methods By building the principle to estimate usability of automated external defibrillators, this research was conducted user observation experiment to measure performance time by step and frequency of error. For this, ways of usage and usage process for empirical study of automated external defibrillators are arranged in this research. The results of the experiments are statically analyzed and combined with the depth interview. Result Control of elements of professionalism and performance pattern of users, and optimization of operation method and movement are selected for the valuation principles to appraise design of automated external defibrillators. As a result of user observation experiment, elements to effect satisfaction, and user satisfaction are differ as models. Conclusion It is helpful to improve understanding of the product and intuitive use, by minimizing or removing perception elements of control part that are not related with operation step. By avoiding interference of each element and giving feedback by tactile perception elements, operation mistakes of users can be prevented. Pace of the audio guidance is synchronized and the audio guidance is repeated until the end of each step. These visual and acoustic methods are helpful to recognize operation step and to minimize mistakes caused by noises. Storage methods of the pad is minimized opening step and is strengthened visual perception methods to shorten operation time and to decrease frequency of error.
