Outline of Final Research Achievements

This study analyzed how the layperson recognize cardiac arrest and expresses it to the dispatcher at the fire department by the internet survey. In cardiac arrest, characteristic words such as "not" whose respiratory status cannot be clearly confirmed were extracted, and in Agonal respiration, words indicating the frequency of breathing such as "occasional" were extracted. For impaired consciousness, words about breathing strength such as "faint" were extracted.
However, words related to mouth movements such as "mouth," "movement," and "pakupaku" (that means action of opening and closing in Japanese) appear in both Agonal respiration and impaired consciousness, and may not be a criterion for judgment.

Academic Significance and Societal Importance of the Research Achievements

本研究の結果から、心停止を目撃した通報者からの通報の中で、心停止を強く疑うべき表現と心停止ではない状況においても発話される表現の違いが理解できる。これらの表現を実用化できるように整理していくことにより、実際の通報者からの通報の中で、消防がより確実に心停止を判断するためのツールとして用いることができ、早期の心肺蘇生法を行うための指導の実施につながる。最終的には救命率の向上に寄与する。
