Abstract

Auscultatory method as a gold standard in determining blood pressure is subjective due to its dependency on hearing ability of each person. This subjectivity could be eliminated by establishing an instrument that is able to determine blood pressure level automatically. One of the ideas that could be proposed for developing an automatic blood pressure monitor is to automatize auscultatory method. This review presented recent development of automatic blood pressure monitor by recording Korotkoff sound and processing it digitally to determine blood pressure level and phases of the sounds that believed was associated with physiological condition. The reviewed studies showed that by processing Korotkoff sounds, the measurement results were accurate if compared with conventional method since their correlation coefficient is greater than 0.95 and the errors that obtained are less than 5 mmHg. The future work of this review is to design a similar instrumentation with different signal processing methods, i.e. discrete wavelet transform and peak finder algorithm.

听诊法自动测量血压的研究进展

听诊法作为测定血压的金标准，因其依赖于每个人的听力能力而具有主观性。这种主观性可以通过建立一种能够自动确定血压水平的仪器来消除。开发自动血压监测仪的思路之一是将听诊方法自动化。本文综述了自动血压监测仪的最新进展，该监测仪通过记录Korotkoff声音并对其进行数字化处理，以确定血压水平和与生理状况相关的声音相位。研究表明，通过对Korotkoff声音进行处理，其相关系数大于0.95，测量结果误差小于5 mmHg，与传统方法相比，测量结果更加准确。本综述的下一步工作是设计一个类似的仪器，使用不同的信号处理方法，即离散小波变换和寻峰算法。
