| Summary: | 碩士 === 中原大學 === 電機工程研究所 === 99 === The main purpose of this thesis is to analyze patient's heart rate variability in home care system, to determine the patient's vital sign, then connect WBAN(wireless body area sensor) and sever by wireless communication system, it can reduce sudden cardiac death no one discovered the cancer.
In this thesis through the low power design in wireless device to obtain information of heart rate variation (HRV) signal .It contains the following three steps: First, we deliver electrocardiogram (ECG) to HRV module’s data by wireless communication. Second, we went to grab the patients ECG signal acquisition heart rate and standard deviation of the averages of NN intervals in all 5 min segments of the entire recording. Third, we input this signal to home care system, to achieve real-time monitoring and warning of abnormal data. If it has been abnormal we’ll inform medical unit by internet to reduce the incidence of accidents. Finally, we’ll show the simulations for this home care system.
1. We can take heart rate and SDANN by wireless communication, to determine physiological state on patient.
2. It can reduce accident when no one at home.
3. It can save more medical resources by this home care system.
