There are two major ways to measure blood pressure during medical treatment : invasive and non-invasive methods. Both them have advantages and disadvantages. For invasive method, it is used for surgical operations. Although it can response the true situation of arterial blood pressure, the damage and uncomfortable are the most disadvantages for itself. And for non-invasive method, it is convenient to use but the measurement results have lower accuracy. In this research, we try to estimate the continuous trend of diastolic pressure utilizing PPG signal. And calculate the accuracy of the results.
