Abstract：Blood pressure is an important physiological index of the human body， in recent years, there has been an increasing demand for non-invasive, cuffless, and continuous blood pressure monitoring devices. A suitable model based on the characteristic parameters of pulse wave can be used to continuously estimate arterial blood pressure by measuring a series of characteristics of pulse such as pulse transmission time of arterial pulse wave. This paper first introduces the principle of blood pressure measurement based on the characteristic parameters of pulse wave, and summarizes the relevant measurement models, such as linear regression model, non-linear regression model, and neural network model, summarizes the research results, introduces the research status of the application of pulse wave technology in cardiovascular diseases, and finally analyzes its future development trend.
