项目摘要

This study examined connection with Lyapunov exponent and a Fractal dimension, analysis results such as entropy and an Immunity function provided from Chaos analysis of a finger plethysmogram pulse wave in daily living. Through these data analysis, we examined whether observation of daily health care and the condition of a patient was possible and performed consideration for the practical use.(1) Practical use to telenursing and effects as nursing informaticsThe purpose of this study was to verify that finger plethysmogram, which is nonlinear data, could be effectively used as vital data in telenursing. The subject was a 58-year-old male patient with type2 diabetes. In this study, chaos analysis was applied to finger plethysmogram and quantitative evaluation of Kolmogorov-Sinai entropy was performed. The type2 diabetes seemed to be getting under control because the morning fasting blood glucose levels and the blood pressure levels declined. However, the Kolmogorov-Sinai entropy indicated that the chaos decreased, which did not link with the improvement of the condition. HbAlC increased from 7.1% to 7.4%. The above-mentioned data indicates that the morning fasting blood glucose levels have decreased but blood sugar was not sufficiently controlled in the course of a day. That is, when finger plethysmogram is used as vital information for patients with diabetes, it would be preferable to judge it in the course of a certain period of time.(2) Effects of practical use as nursing informaticsIn medical facilities, observation of vital signs information is performed routinely. Therefore we examined non-linear chronological order information taken for observation how chaos analysis of the finger apex pulse wave that we developed this time was availability at the clinical top. As a result, that there was connection with Immunity to become an index of a healthy degree was suggested.

本研究探讨了与李雅普诺夫指数和分形维数的连接，分析结果，如熵和免疫功能提供了从混沌分析的手指脉搏波在日常生活中的体积描记图。通过这些数据分析，我们研究了日常保健和患者状况的观察是否可行，并考虑了实际应用。(1)远程护理的实际应用及作为护理信息的效果本研究的目的是验证手指体积描记图，这是一种非线性数据，可以有效地作为远程护理的重要数据。该受试者是一名58岁的男性2型糖尿病患者。在这项研究中，混沌分析应用于手指体积描记图和定量评价Kolmogorov-Sinai熵。2型糖尿病似乎得到控制，因为早晨空腹血糖水平和血压水平下降。而Kolmogorov-Sinai熵则表明混沌程度有所降低，但这与条件的改善无关。HbAlC从7.1%增加到7.4%。上述数据表明，早晨空腹血糖水平已经降低，但血糖在一天中没有得到充分控制。也就是说，当手指体积描记图被用作糖尿病患者的生命信息时，优选在一定时间段的过程中对其进行判断。(2)作为护理信息学的实际应用效果在医疗设施中，定期进行生命体征信息的观察。因此，我们研究了非线性时间顺序信息，用于观察我们这次开发的手指尖脉搏波的混沌分析在临床上的可用性。结果表明，免疫力与健康程度有关，可作为健康程度的一个指标。
