Outline of Final Research Achievements

We successfully generated and evaluated the lung sounds of COVID-19 and other respiratory diseases by a novel wireless stethoscope with its cloud system during the clinical course, which demonstrated the healing process of those pneumonia along with the improvement of the clinical symptoms and heart-resolution computed tomography findings. This was characterized by the change of the timing of inspiratory crackles from “mid to late” to “late” inspiratory crackles. This novel system could be applied for the patient management between tertiary center and home medical care, even in a setting of COVID-19 era.

Academic Significance and Societal Importance of the Research Achievements

患者のマネージメントにおいて、診療所ー在宅患者、診療所ー基幹病院との患者の呼吸状態の把握に寄与する新たな遠隔医療システムを開発した。本システムを通じて、在宅医療の現場ででも、新たな聴診器を使用しリアルタイム に呼吸音データの共有が可能であることを確認し（例：東京―埼玉明間など）、将来的には患者の迅速な対応へと繋がる副雑音の早期発見や臨床経過の予測に使用できる可能性を示した。
