Design and development of a new embedded ambulatory blood pressure monitoring system

提出一种基于ARM Cortex-M3的嵌入式动态血压监测仪的设计方案。该方案采用高斯分布曲线对人体脉搏波包络进行拟合,通过优化高斯分布参数和状态反馈参数,提高了算法运算速度和精度,实验结果表明新型的嵌入式动态血压监测仪具有精度高、重复性好、抗干扰能力强等特点。

This paper proposes a design program of embedded dynamic blood pressure monitor based on ARM Cortex-M3. An improved algorithm is put forward in this scheme ,which uses Gauss distribution curve to fit the envelope of human pulse wave. The experimental results show that the method is effective.
