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.
