In the present work, we report a novel, in vivo, noninvasive technique to determine radial arterial compliance using the radial arterial pressure pulse waveform (RAPPW) acquired by fiber Bragg grating pulse recorder (FBGPR). The radial arterial compliance of the subject can be measured during sphygmomanometric examination by the unique signatures of arterial diametrical variations and the beat-to-beat pulse pressure acquired simultaneously from the RAPPW recorded using FBGPR. This proposed technique has been validated against the radial arterial diametrical measurements obtained from the color Doppler ultrasound. Two distinct trials have been illustrated in this work and the results from both techniques have been found to be in good agreement with each other.
在本研究中，我们报告了一种新颖的体内非侵入性技术，该技术利用光纤布拉格光栅脉搏记录仪（FBGPR）采集的桡动脉压力脉搏波形（RAPPW）来测定桡动脉顺应性。在血压测量检查期间，通过动脉直径变化的独特特征以及从使用FBGPR记录的RAPPW中同时获取的逐搏脉压，可以测量受试者的桡动脉顺应性。该技术已针对从彩色多普勒超声获得的桡动脉直径测量结果进行了验证。本研究展示了两项不同的试验，并且发现两种技术的结果彼此高度一致。
