摘　　要：目的改进脉搏波无创检测仪的检测方式,考虑到桡动脉检测的操作复杂,因而选择操作简便的指脉检测。方法通过大量的临床数据分析,确定指脉检测方式与桡动脉检测方式之间的转换关系,计算基于容积脉搏波的部分血流动力学参数,并和超声心动检测结果进行对比。结果用指端容积脉搏血流方法同步检测的血流参数和超声心动检测血流参数的结果对比,差异没有统计学意义。结论所得结果表明,在应用指端容积脉搏血流方法检测心输出量及其他血流参数是可行的。Objective Pulse waveform eontains a lot of important hemodynamic information, Using radial artery deteetion to collect pulse wave is more difficuh than using finger detection. So we choose finger detection as the method of pulse wave collection. Methods By mean of statistical analysis of large clinical data, compute the conversion between radial artery detection and finger detection, and contrast belween hemodynamic parameter results based on volume pulse wave and uhrasound detection results. Results The statistical analysis shows that there is no statistical difference between volume pulse wave deteetion and ultrasound deteetion. Conclusion Finger volume pulse blood deteetion method can be used as detection of cardiac output and other hemodynamic parameter.
