Cardiovascular disease is one of the important factors that threaten the health of residents, ranking first among various causes of death, so the monitoring and diagnosis of human cardiovascular health is particularly important. Compared with traditional brachial artery pressure, central arterial pressure (CAP) has a higher correlation with the occurrence of many cardiovascular events. The measurement of central arterial pressure can more accurately reflect the real situation of human blood pressure, And provide an important basis for diagnosis and disease prevention. Therefore, the realization of high-precision, high-generalization ability, and low-cost non-invasive measurement of central arterial pressure has always been the focus of research in this field. This article combines the relevant literature at home and abroad to summarize the current status of central arterial pressure measurement, introduces related research progress from two aspects of parameter measurement and waveform measurement, and discusses the characteristics of the existing methods and the future development direction.
