【摘要】应用非损伤光电体积描记技术(PPG),测量人体姿态在仰卧和45°斜躺、下肢被动地放到不同高度位置时,脚趾端的血液脉搏信号.得出了两种姿态下脚趾端PPG信号随下肢位置高度的变化情况,并绘成关系曲线图.更多还原

【Abstract】 Under two body-postures:supine and 45°reclining,the blood pulse signal on toe was detected via non-invasive photoplethysmog raphy technique while the lower limb was passively raised in different height.The regulations of blood pulse volume and lower limb height were found and their relation was described through curves in figures.更多还原
