摘要
分析影响监护仪显示的各项参数及图像因素。认为电极接触不良及干扰、仪器感知功能不良是影响心率及心律显示准确的主要因素，测量部位、袖带松紧度及病人体位是影响血压显示准确的因素。
The factors influencing the every parameter and image of electrocardiographic(ECG) machine were analysed.It is considered that the electrode loose contact and interference,and the perception disfunction are the main influencing factors on the displaying accuracy of heart rate and rhythm.According to the practice,the methods recognizing and debugging the influencing factors are suggested.
