Accurate non-invasive measurement of blood pressure in unsupervised environments continues to be a challenge, particularly in the presence of movement artefact, electrical noise and most importantly cardiac arrhythmia which are common in those aged over 65 suffering from a range of chronic conditions. Large intra personal variability in signal morphometry and amplitudes further complicates the development of reliable signal processing algorithms for NIBP measurement. In this paper we demonstrate the effect of this variability and propose that the traditional methods of human blood pressure determination by sphygmomanometry should no longer be considered a gold standard for the calibration of NIBP devices.
在无人监督的环境中准确进行无创血压测量仍然是一项挑战，尤其是存在运动伪影、电噪声，最重要的是存在心律失常时，而心律失常在65岁以上患有一系列慢性疾病的人群中很常见。信号形态和幅度存在较大的个体内差异，这进一步使用于无创血压测量的可靠信号处理算法的开发变得复杂。在本文中，我们展示了这种差异的影响，并提出传统的通过血压计测定人体血压的方法不应再被视为校准无创血压测量设备的金标准。
