摘要

在本文中,我们开发了一种创新算法来改进示波波形检测,从而提高血压(BP)测量的准确性。大多数血压测量技术都是基于从袖带中产生的基线压力中提取振荡波形(OMW)。人体的生理变化会使 OMW 呈现出不规则的形状、幅度和模式。除了人体生理活动外,运动伪影也可能在血压测量过程中影响 OMW。使用直接提取法测量血压,然后再构建包络线,会出现明显的误差,超出允许范围。为了解决这个问题,需要一种新的算法。这项工作展示了一种通过创建零基线来改进 OMW 的新算法。所提出的算法适用于从低到高的血压值,其结果优于用于 OMW 的传统算法。通过所开发的算法获得的收缩压和舒张压值均在美国医学仪器促进协会/欧洲高血压学会/国际标准化组织(AAMI/ESH/ISO)等国际协议规定的误差范围内。

Development of an Innovative Algorithm for Accurate Measurement of Human Blood Pressure

In the present paper, we have developed an innovative algorithm to improve the oscillometric waveform detection to increase the measurement of blood pressure (BP) accuracy. Most of the techniques for BP measurement are based on the extraction of the oscillometric waveform (OMW) from baseline pressure generated in the cuff. The physiological changes in the human body provide irregular shapes, magnitudes, and patterns in OMW. Besides human physiological activities, motion artifacts may affect the OMW during the BP measurement. The BP measurement using direct extraction followed by envelope construction shows significant errors beyond the permissible limits. To rectify this problem, a new algorithm is required. This work demonstrates a novel algorithm to improve OMW by creating a zero baseline. The proposed algorithm is performed on low to high BP values, giving better results than the conventional algorithm used on OMW. The systolic and diastolic values of blood pressure obtained from the developed algorithm are within the error limits of international protocol, i.e., American Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO).
