Fetal heart rate monitoring failed? Probably because of this sharing today.
In fact, when we reach the third trimester of pregnancy, we all regularly do fetal heart rate monitoring. This fetal heart rate monitoring is one of the most commonly used tools in our clinical practice to assess fetal intrauterine safety. Its biggest advantage is that it has neither pain nor damage, and it can dynamically observe the changes in the fetal heart rate of the fetal heart. However, it has a very obvious disadvantage, that is, the false anomaly rate is relatively high. Why do you fail once? Do our doctors still have to keep you reviewed? His false anomaly rate is relatively high. Our doctors perform multiple tests to rule out these false abnormalities.
Why do false anomalies occur? It is when he is particularly quiet, the baby's sleeping state will appear unideal fetal heartbeat, and then the pregnant woman's mood is too tense and anxious, and when the pregnant woman's heart rate is very fast, the baby will also have a false abnormal situation of fast heartbeat. Some, such as when we use sedatives, the baby's fetal heart rate will also be affected. So his disadvantage is that the false anomaly rate is very high.
In order to eliminate the false abnormality rate, the doctor will repeatedly detect the undesirable pattern, and the ideal fetal heart rate monitoring will appear to determine that the baby is safe. Therefore, the credibility of the abnormal fetal heart rate monitoring map is relatively low, and after repeated review of the fetal heart rate monitoring, as long as there is a good, normal ideal fetal heart rate monitoring map. The credibility of this guardianship chart is very high, indicating that the baby is relatively safe for a period of time.
In addition, we assess whether the baby is safe, not only look at the fetal heart rate monitoring chart, we also look at the size of the baby, the blood flow in the umbilical cord, and the amount of amniotic fluid comprehensive judgment. If the composite indicators all point to the baby being safe, you don't have to worry about it.
