The embodiment of the invention discloses a method and equipment for measuring the blood pressure of a central artery. The method comprises the steps of measuring the change of blood pressure waveformof a peripheral artery with time; acquiring the flowing time of blood flow from the central artery to a blood pressure measurement position of the peripheral artery; according to the blood pressure waveform of the peripheral artery and the flowing time, calculating the blood pressure waveform of the central artery. In this way, the calculation amount for measuring the blood pressure waveform of the central artery is small, and only the blood pressure of the single peripheral artery needs to be measured, so that the measurement difficulty is low, convenience is provided for use, the measurement cost can be reduced, and individual differences can be reflected.
Description
technical field [0001] The embodiments of the present invention relate to the field of biomedical engineering, in particular to a method and device for measuring central arterial blood pressure. Background technique [0002] Central arterial blood pressure (CAP) is a disease predictor independent of brachial artery blood pressure. It plays a direct role in predicting the degeneration of arterial function caused by hypertension. In recent years, studies have found that central arterial blood pressure evaluates the treatment effect of hypertension and the prognosis of the disease. , arterial structure and function are more accurate than traditional arm brachial artery blood pressure measurement, and its clinical value is higher. [0003] The inventors of the present invention have found in long-term research that the dual-peripheral central arterial blood pressure measurement method adopted in the prior art needs to measure double peripheral arterial blood pressure, which requ...
