Is it serious if fetal heart rate monitoring fails?

Pregnant women need to undergo regular examinations during pregnancy, and fetal heart rate monitoring is one of them. The function of fetal heart rate monitoring is to better understand the growth and development of the fetus in the uterus, so as to understand the current condition of the fetus. Is there any risk if the fetal heart rate monitoring fails?

Are there risks if fetal heart rate monitoring fails?

Whether the fetal heart rate monitoring failure is serious depends on the situation.

1. If the fetal heart rate exceeds 160 or is below 100 for a long time, more than five minutes, it should be taken seriously. If necessary, a caesarean section should be performed as soon as possible to remove the fetus to avoid intrauterine hypoxia and suffocation of the fetus.

2. If the fetal heart rate fluctuates occasionally, but it affects the score, don't worry too much. At this time, the doctor will usually ask you to do fetal heart monitoring again after an hour, or arrange for you to do other tests.

The main manifestations of abnormal fetal heart monitoring

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

2. During fetal heartbeat monitoring, if an abnormality is found in the fetal heartbeat pattern, it is often used to indicate that the fetal heartbeat is abnormal.

Note: In most cases, abnormal fetal heartbeat means that the fetus is suffering from insufficient oxygen in the uterine cavity. The more severe the abnormal fetal heartbeat is, the more severe the fetal intrauterine hypoxia is. However, not all abnormal fetal heartbeat is caused by insufficient oxygen.

Fetal heart rate monitoring function

Fetal heart rate monitoring is the general name for the fetal heartbeat, fetal movement and uterine contraction graph. It uses a fetal heart rate electronic electrocardiogram monitor to record the fetal heart rate curve and uterine contraction pressure waveform for clinical analysis. It is an important test method to accurately assess the fetal intrauterine condition. It plays a key role in early detection of fetal heartbeat abnormalities, proper treatment and reduction of perinatal mortality.

There are two main channels for fetal heart monitoring:

The upper one is the fetal heart rate, which fluctuates between 120-160 under normal circumstances. It is usually shown as a straight line with a basic heartbeat line. When the baby moves, the heartbeat will increase, forming an upward convex curve. After the baby moves, it will gradually decrease. The number of fetal movements is >30 times/12 hours, which is normal, and <10 times every 12 hours indicates fetal intrauterine hypoxia.

The lower line shows the intrauterine pressure, which increases during contractions and then remains around 20 MmHg.

In addition to the fetal heart rate monitoring performed during each prenatal checkup, you can also perform it at home. As long as you buy a fetal heart rate monitor, you can check your baby's development anytime and anywhere.
