Home blood pressure monitoring using electronic blood pressure monitor is an important way to prevent serious cardiovascular events. Wrist blood pressure monitor which has the following advantages: low price and easy to use, is ideal equipment for blood pressure self-monitoring. Institute of Intelligence Machines, Chinese Academy of Sciences is developing low-cost health promotion system based on the management of way of life for chronic disease prevention and control, blood pressure measurement module is an important part of the system. By research of the existing electronic blood pressure monitor, we found it is necessary to develop a new wrist blood pressure monitor, because: (1) precision problem: existing electronic blood pressure monitor determined blood pressure only by a simple method, accurate and repeatability of blood pressure monitor need to be improved; (2) interface problem: the low-cost health promotion system based on the management of way of life require the blood pressure measurement module connected to the system by private interface. In order to develop a wrist blood pressure monitor which has high-precision, and can be used for home blood pressure monitoring and chronic disease prevention and control, this thesis proposed a method for determining blood pressure based on oscillometric method and Gaussian fitting, and developed a
