- Abstract:
- Abstract: Objective To design a continuous blood pressure measurement method for non-invasively monitoring the blood pressure of subjects in real time. Methods After the feature identification of the pulse waves of the posterior auricular artery and the dorsal digital artery, the transit time between the two pulse waves was calculated, and then the pulse wave velocity was obtained according to the patients physiological information such as blood density, blood vessel diameter and blood vessel wall thickness. Finally, based on the traditional pulse transit time algorithm, the height and weight of subjects were taken into consideration for calculating the blood pressure of the human body. Results Using the proposed method could obtain the blood pressure which was close to the real value, with a good real-time performance. Conclusion The improved blood pressure measurement method based on pulse transit time can be used to realize real-time blood pressure measurement, providing helps for clinical diagnosis.
