Abstract

Brachial Augmentation Index (BAI) is a known indicator of brachial arterial stiffness. BAI depends on the speed of travel of the blood pressure wave during a cardiac cycle, which is decided by the elasticity of the brachial artery. Evaluation of BAI is necessary as a part of cardiovascular diagnosis, in view of its established capability to forecast cardiovascular diseases. The present study proposes a novel non invasive beat-to-beat brachial arterial pulse pressure waveform (BAPPW) evaluation methodology using Fiber Bragg Grating Sensor. Fiber Bragg Grating Pulse Recorder (FBGPR) is employed to acquire the BAPPW, which has the ability to transduce the pressure in the pulsating brachial artery into strain variations on a silicone diaphragm. The recorded BAPPW is analyzed to obtain the diastolic pressure and systolic pressure indicated by the lowest and the peak point of the BAPPW respectively. The late systolic pressure also known as the augmented pressure is the reflected wave from the peripheral points. The ratio of the late systolic pressure to the systolic pressure is defined as the BAI, which may be evaluated beat-to-beat using FBGPR. The present work is a feasibility study of effective employment of FBGPR for obtaining the BAPPW along with the evaluation of the BAI and heart rate.
