Outline of Final Research Achievements

We attempted to develop a smartphone application to improve the ability to recognize the signs of cardiac arrest using augmented reality (AR) technology, which has developed rapidly in recent years. The application was developed in collaboration with a partner company, and the corresponding operating system was iOS (Apple Inc.), which can be used on an iPhone or iPad. The actions of the wounded and sick people appearing in the application were recorded by motion capture and three-dimensional computer graphics (3DCG) were created. The characteristic movement of the lower jaw seen during death breathing was created using video footage of real casualties as a reference. A series of CPR procedures can now be practiced on a smartphone.

蘇生教育

Academic Significance and Societal Importance of the Research Achievements

心停止の現場に居合わせた市民が死戦期呼吸を「呼吸がある」と判断し、心肺蘇生を躊躇あるいは必要ないと判断することが報告されている。また、住宅で発生した心停止の予後は極めて不良である。これらを解決する一つの手段として、スマートフォン上のアプリを用いて死戦期呼吸を評価・判断し、心肺蘇生およびAEDの使用を実践するという新たな心肺蘇生教育により、これまでに普及していなかった領域に蘇生教育を普及させることが可能となった。今後、社会実装することで病院外心停止患者の救命率向上に寄与することが期待される。
