对于心血管疾病,特别是心血管急症,如急性心肌梗塞、急性心力衰竭、休克等等,以及心脏外科手术前后,如何从心功能状态和血液动力学方面进行无创性的连续监测,是临床医学一个突出的问题,虽然从本世纪40年代以来心导管技术发展很快,但仍不能满足对心功能和血液动力学进行无创性连续检测的要求,因而人们又注意到从主动脉压力和流量关系中进行研究,以便能同时得到每搏心输出量、心脏功率、外周阻力、心室肌肉收缩情况等参数。
For cardiovascular diseases, especially cardiovascular emergencies such as acute myocardial infarction, acute heart failure, shock and so on, and how to conduct noninvasive and continuous monitoring of cardiac function and hemodynamics before and after heart surgery, One prominent issue is that although cardiac catheterization has developed rapidly since the 1940s, it still can not meet the requirement of noninvasive and continuous detection of cardiac function and hemodynamics. Therefore, people also noticed that the relationship between pressure and flow in the aorta In order to be able to simultaneously get stroke cardiac output, cardiac output, peripheral resistance, ventricular contraction and other parameters.
