Abstract

Heart- and respiration rate related signals were measured simultanously using reflection mode of photoplethysmography (PPG) through a fiber optic sensor. The sensor was attached to the ear-lobe. Both heart- and respiration related variations in blood perfusion could be observed after filtering the PE signal. The frequency content of the signal was observed by calculating the power spectral density.

使用光纤传感器监测心脏和呼吸速率

通过光纤传感器，采用反射模式光容积脉搏波(PPG)同时测量心脏和呼吸频率相关信号。传感器安装在耳垂上。在PE信号滤波后，可以观察到心脏和呼吸相关的血流灌注变化。通过计算功率谱密度来观察信号的频率含量。
