我们建立了一个合理的健康监护系统，脉搏波和呼吸分析，以评估血管状况和自主神经功能在日常生活中。考虑到脉搏传感器的个体差异以及系统作为可穿戴设备和应用的潜力，精心设计了具有红外传感器的滤波电路，以完成外周脉搏波的测量和分析。我们系统的分析仪能够预测动脉状态和僵硬度。具有呼吸起搏器的用户界面可以辅助自主呼吸，可视化脉搏波特征，并真实的实时调节它们。用户界面软件具有广泛的兼容性，可以轻松应用于移动的医疗设备。我们还评估了呼吸控制如何反映脉率变异性[即，与自主神经系统相关的峰-峰间期（PPI）波动。使用创建的带有呼吸起搏器的用户界面进行了不同呼吸速率下的实验研究。PPI的传递增益在0.1Hz的呼吸速率下引起共振（p< 0.5），对应于心脏的充分刺激的迷走张力。模拟研究表明，模糊推理表明呼吸调节的鲁棒性，以最大限度地提高PPI振荡的振幅下，包括个体差异和意外的反应。作为未来的展望，用于调节脉搏波特征的呼吸起搏器可以应用于有效的恢复支持系统，特别是在诸如精神应激和缺氧的自主神经功能减弱的情况下。
We constructed a reasonable healthcare monitoring system with pulse wave and respiratory analysis to assess blood vessel conditions and the autonomic function in daily life. Filter circuits with an infrared sensor were carefully designed to complete the peripheral pulse wave measurement and analysis, considering individual differences to a pulse sensor and the potential for the system to be used as wearable devices and applications. The analyzer for our system is capable of predicting arterial states and stiffness. A user interface with a respiratory pacemaker can assist voluntary breathing, visualize pulse wave features, and regulate them in real time. The user interface software is widely compatible and could be easily applied to mobile healthcare devices. We also evaluated how respiration control reflected pulse rate variability [i.e., fluctuations inpeak-to-peakintervals (PPI)] associated with the autonomic nervous system. An experimental study under various breathing rates was performed using the created user interface with a respiratory pacemaker. The transfer gain of the PPI caused resonance at the respiratory rate of 0.1 Hz (p< 0.5), corresponding to the sufficiently stimulated vagal tone of the heart. A simulation study revealed that the fuzzy inference indicates the robustness of respiratory regulation to maximize the amplitude of PPI oscillations under the inclusion of individual difference and unexpected response. As future perspective, the respiratory pacemaker used to regulate the pulse wave feature could be applied to an effective recovery support system especially under blunted autonomic function such as during mental stress and hypoxia.
