摘要:: 心输出量（CO）是人体血流动力学监测的核心参数，对心血管疾病的诊断和治疗具有重要意义，而脉搏波包含了丰富的生理病理信息，其波形特征与血流动力学参数的变化密切相关，因此在CO监测上有着广泛的应用。脉搏波主要分为压力脉搏波和容积脉搏波两类，前者在CO监测上已有成熟的产品，后者则仍在科研阶段，尚未有能满足应用要求的技术产品。本文首先分别介绍压力脉搏波和容积脉搏波各自的特点以及计算CO的理论基础，然后从微创及无创两个方面，介绍几种基于两类脉搏波的CO监测技术，并分析它们的基本原理和优缺点，最后对监测技术的发展和应用做了展望。

Abstract:: Abstract: Cardiac output (CO) which is the core parameter of human hemodynamic monitoring is of great significance for the diagnosis and treatment of cardiovascular diseases. Pulse wave contains a wealth of physiological and pathological information, and its waveform characteristics are closely related to the changes in hemodynamic parameters, so pulse wave has a wide range of applications in CO monitoring. Pulse wave is mainly divided into two types, namely pressure pulse wave and volume pulse wave. The former has mature applications in CO monitoring, while the latter is still in the stage of scientific research, and there is no technical product that can meet the application requirements. Herein the characteristics of pressure pulse wave and volume pulse wave are introduced, and the theoretical basis of the CO calculation based on pressure wave and volume wave are revealed. Several CO monitoring techniques based on two types of pulse waves are also introduced from the aspects of minimally invasive and noninvasive, and the basic principles, advantages and disadvantages of different techniques are analyzed. Finally, the developments and applications of CO monitoring technology are discussed.
