一、胎儿分娩监护仪的意义和要求为了减少围产期的胎儿死亡率,国外一些国家普遍使用胎儿分娩监护仪。过去使用听诊器来了解胎儿心跳次数的方法有很大的局限性。例如,当子宫收缩时就很难听到胎儿的心跳声,而这段期间胎儿的心跳变化情况对临床诊断却有着很重要的意义。早期的分娩监护仪就是为了能连续掌握胎儿的心跳变化而设计的。一般认为正常胎儿每分钟的心跳次数为120~160次,其分类如表1所示。但单纯的胎心率不能完全说明胎儿情况,而胎心率变
First, the meaning and requirements of the fetus childbirth monitor In order to reduce perinatal fetal mortality, some countries in foreign countries generally use the fetus childbirth monitor. In the past, the use of stethoscopes to understand the frequency of fetal heart rate has its own limitations. For example, it is difficult to hear the heartbeat of a fetus when the uterus contracts, and the changes in fetal heart rate during this period are of great importance for clinical diagnosis. Early childbirth monitors were designed to keep track of changes in fetal heart rate. Generally believed that the normal fetal beats per minute heart rate 120 to 160 times, its classification as shown in Table 1. However, a simple fetal heart rate can not fully explain the situation of the fetus, while changes in fetal heart rate
