摘要
:脉搏血氧仪中光电容积脉搏波的正确提取和检出是完成氧饱和度测量任务的主要环节之一 .为了克服传统设计中采用硬件电路完成脉搏波提取和检出时所带来的系统整体设计复杂 ,稳定性和重复性差等缺点 ,作者研究了光电容积脉搏波的软件提取和检出方法 。
Correct extraction of the photoplethysmography is one of the primary procedures to measure the oxygen saturation in the pulse oximeter. In order to overcome the problems of complex system design, instability and bad repetition which are brought about by analog circuits for completing the photoplethysmography extraction in conventional pulse oximetry systems, the author studied the software method to extract the photoplethysmography which will be the basis for digitizing the design of the pulse oximetry systems.
