监测心输出量的变化,是观察判断心脏功能的重要血流动力学指标.作者应用TP—CBS型心血管血流参数检测仪,通过动物实验与临床常用的有创心输出量检测法——热稀释法及电磁流量计法进行同步测试比较,以验证这种无损伤脉波法对心输出量检测的准确性和可信性,为临床推广应用提供实验依据.通过16只犬的对照性测试结果,与热稀释法比较相关系数(r)在0.7～0.9之间.与电磁流量计法比较相关系数(r)在0.8～0.9之间,得到了较好的相关性.表明应用无创伤脉波法监测心输出量,对临床判断心功能有重要参考价值.
Monitoring changes in cardiac output, is to observe the important hemodynamic indicators to determine cardiac function.Application of TP-CBS type of cardiovascular blood flow parameters of the detector, through animal experiments and clinical commonly used invasive output detection method - Thermal dilution method and electromagnetic flowmeter method to compare the synchronous test to verify the accuracy of this non-invasive pulse wave detection of cardiac output and credibility, to provide experimental evidence for clinical application.Carrying through 16 dogs The test results showed that the correlation coefficient (r) was 0.7 ~ 0.9 compared with the thermal dilution method, and the correlation coefficient (r) was 0.8 ~ 0.9 with the electromagnetic flowmeter method, which showed that the correlation was good Pulse wave monitoring of cardiac output, the clinical evaluation of cardiac function has an important reference value.
