示波法血压测量技术研究进展

Research Progress of Blood Pressure Measurement by Oscillometric Method

血压是能反映出人体心脏和血管功能的重要生理指标。相比于其它方法,示波法具有抗噪能力强,操作简单和成本较低的优点,是目前应用最为广泛的血压测量技术。该文对近年来采用示波原理测量血压的关键技术进行了概述和讨论,即振荡波包络前处理方法和血压估计技术。其中估计技术包括传统示波法,基于波形形态学的方法,基于模型的方法和机器学习的方法。最后对其未来发展方向进行了展望。

Blood pressure is an important physiological index that can reflect the function of the heart and blood vessels. Compared with other methods, oscillometric measurement has the advantages of strong noise immunity, simple operation and low cost, which is the most widely used technology for blood pressure measurement. In this paper, we reviewed and discussed the key technologies of measuring blood pressure, such as pre-processing method of oscillation envelope and blood pressure estimation technique. The latter include traditional wave method, waveform morphology method, the methods based on the model and machine learning. At last, we have a look forward to its future development direction.
