What to do if fetal heart rate monitoring is unqualified? Mothers must know

Fetal heart rate check is a must-do examination for pregnant women during pregnancy, as it can detect fetal abnormalities at any time. So what should mothers do when the fetal heart rate monitoring shows unqualified results? In fact, unqualified fetal heart rate monitoring means that there is something abnormal with the fetus in the uterus. Mothers must pay attention at this moment!

Since the fetal heart monitoring is unqualified, we should consider that there is something wrong with the fetus in the uterus and pay special attention to the re-examination, or further examination should be done to find the exact cause and actively treat the symptoms. If necessary, you can also go to the next level hospital for re-examination. Only when the fetal heart monitoring is qualified can you rest assured.

When doing fetal heart monitoring, everyone should pay attention to the two lines. The upper line represents the fetal heart rate, and the lower line represents the intrauterine pressure. Under normal conditions, the fetal heart rate is a wavy straight line, and fluctuations between 120-160 are considered normal. If the baby's fetal heart rate fluctuations are within this range within 20 minutes of fetal heart monitoring, then there is no problem.

However, if the baby's fetal heart rate does not change, or does not move for a long time, then this is what we call unqualified fetal heart monitoring. At this time, the doctor will usually do another fetal heart monitoring for you one hour later, or arrange for you to do other examinations. If your doctor thinks your baby is not doing well, he or she may recommend inducing labor. In fact, you can also do fetal heart monitoring at home. You can go to a pharmacy or hospital to buy some related home devices and check it at home at any time to have a better idea of ​​the situation.

Abnormal findings on fetal heart rate monitoring

The normal fetal heart rate is between 120 beats/minute and 160 beats/minute. If the fetal heart rate remains <120/minute or >160/minute for more than 10 minutes, it indicates that the fetal heart rate is abnormal.

During fetal heart monitoring, if an abnormality is found in the fetal heart graph, it is often used to indicate fetal heart abnormality. In most cases, abnormal fetal heart rate means that the fetus is suffering from hypoxia in the uterus. The more severe the abnormal fetal heart rate, the more severe the fetal hypoxia. However, not all abnormal fetal heart rate is caused by hypoxia.

In addition to the above situations, the condition of the pregnant woman herself also affects the changes in the fetal heart rate. For example, if the pregnant woman has a fever, the fetal heart rate will often exceed 160 beats/minute. If the pregnant woman has hyperthyroidism, her own heart rate is very fast, and the fetal heart rate will often exceed 160 beats/minute. If the pregnant woman takes certain medications, such as salbutamol taken during premature delivery to preserve the fetus, or atropine, it can cause the mother and child's heart rate to accelerate. In addition, in the case of umbilical cord entanglement, the entanglement may sometimes be aggravated due to fetal movement, and the fetal heart rate may continue to accelerate. This entanglement may be transient. If it occurs after 36 weeks, the fetus's position is relatively fixed and this entanglement can cause fetal distress or even death.

In addition, after more than 40 weeks of pregnancy, due to problems in the development of the fetal nervous system, the fetal heart rate may sometimes be lower than 120 beats/minute. Therefore, when there is an abnormal fetal heart rate, it is necessary to carefully analyze the situation, make correct judgments and deal with it. If fetal hypoxia does exist, delivery should be carried out as soon as possible.
