Abstract

Mathematical derivation of calculating blood flow volume (BFV) at arteriovenous fistula (AVF) using a newly-developed photoplethysmography (PPG) sensor is presented in this work. Also, the readout circuit of the PPG sensor intended to increase the signal-noise ratio (S/NR) is designed and presented in this work. The designed PPG sensor equipped with derived mathematical equations shows high correlation (R2 = 0.7563) and low error (RMSE = 212 ml/min) as compared to the gold standard.

应用新型光容积脉搏波传感器测量血液透析(HD)患者动静脉瘘(AVF)血流量(BFV)的数学推导、电路设计及临床实验

本文介绍了一种新开发的光容积脉搏波(PPG)传感器在动静脉瘘(AVF)处计算血流量(BFV)的数学推导。此外，本文还设计并介绍了用于提高信噪比(S/NR)的PPG传感器读出电路。与金标准相比，所设计的PPG传感器具有较高的相关性(R2 = 0.7563)和较低的误差(RMSE = 212 ml/min)。
