摘　　要：为了摆脱传统血压计充气袖带的束缚、实现长期连续的血压监测,很多学者开展了基于PPG实现无创、连续血压监测的研究。阐述基于光电容积脉搏波描记法(PPG)实现无创、连续血压测量的基本原理。将当前基于PPG无创血压监测的研究分为3类,分别为心电(ECG)与PPG结合的血压测量技术、两路PPG结合的血压测量技术、脉搏波特征参数血压测量技术,分析这3类技术的基本测量原理、测量精度及其优缺点。在此基础上,论述基于PPG实现无创、连续监测血压的发展方向。Noninvasive and continuous blood pressure monitoring have been intensively investigated and developed in attempt to getting rid of inflatable cuff and realizing the long term blood pressure monitoring. This article analyzed the principle of noninvasive and continuous blood pressure measurement based on photoplethysmography （PPG）. The researches of current noninvasive blood pressure monitoring based on the PPG ware claasi fled into three categories including combination of electrocardiograph （ECG） and PPG, two channels PPG, and utilization of pulse characteristic parameter. The measurement accuracy, advantage and disadvantage of the three technologies were summarized. The development tendency of the noninvasive and continuous monitoring blood pressure based on the PPG was discussed.
