摘　　要：基于超声波的相对血容量检测可用于血液透析患者干体重的评估,相对血容量计算结果来自于超声波在动脉壶中传播时间的测量,而传播时间测量的准确性直接关系到相对血容量结果的可靠性。影响传播时间的因素是多方面的,该文从患者本身、检测装置和外界因素等方面进行了分析论证,并提出了适当的应对措施。Ultrasound-based measurement of relative blood volume can be used to assess patient＇s dry weight during hemodialysis. The results of relative blood volume were calculated from the ultrasonic transmission time measurement in the arteriol pot, and the accuracy of transmission time measurement is directly related to the reliability of the results of relative blood volume. There are various factors which influence the travel time, this article analyzed patients themselves, measuring device and the external factors, and advised appropriate counter measures.
