Abstract：Objective To establish a continuous blood pressure measurement model based on personalized pulse wave transmission parameters. Methods ECG parameters and finger pulse waves of 18 subjects were continuously measured and recorded in exercise tests and their blood pressures (BP) were also recorded every 2 minutes with dynamic BP monitor. The exercise tests of all the 18 subjects were conducted repeatedly one week later. A linear model between pulse wave translation time (PWTT) and systolic blood pressure (SBP) was constituted through linear minimum mean square error estimation. Results There is a good linear relationship between PWTT and SBP of the same subject (r2=0.91±0.06) and the test error of the linear model with nice stability is (3.48±1.69) mmHg. However, it is very difficult to build a unified linear model for all subjects (r2=0.14). Conclusion It is feasible to measure blood pressure continuously based on personalized pulse wave transmission parameters, which can contribute to the realization of sleeveless continuous blood pressure measurement.
