Application to nursing informatics by chaos analysis of a finger plethysmogram

本文研究了日常生活中手指体积脉搏波的混沌分析与李雅普诺夫指数和分形维数的联系，以及熵和免疫函数等分析结果。通过这些数据分析，我们考察了是否有可能观察患者的日常保健和病情，并对实际应用进行了考虑。(1)在远程护理中的实际应用及其作为护理信息的效果。本研究旨在验证手指体积谱这一非线性数据在远程护理中的重要应用价值。研究对象是一名58岁的2型糖尿病男性患者。本研究将混沌分析应用于手指体积谱，并对Kolmogorov-Sinai熵进行定量评价。2型糖尿病似乎得到了控制，因为早晨空腹血糖水平和血压水平下降了。然而，Kolmogorov-Sinai熵表明混沌减少，这与条件的改善无关。HbAlC从7.1%上升到7.4%。上述数据表明，早晨空腹血糖水平有所下降，但血糖在一天的过程中没有得到充分控制。也就是说，当手指体积描记图作为糖尿病患者的重要信息时，最好在一定的时间内进行判断。(2)作为护理信息学的实用效果在医疗机构中，生命体征信息的观察是常规的。因此，我们检查了非线性时间顺序信息，以观察我们这次开发的指尖脉冲波的混沌分析如何在临床顶端可用。因此，建议将免疫作为健康程度的指标。

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.
