Hypoxia fetal heart rate monitoring diagram

Fetal heart rate monitoring uses microwave technology and is harmless to children. Fetal heart rate monitoring can be used to monitor the baby's heartbeat during fetal movement and uterine contraction, so as to determine whether the fetus is suffering from insufficient oxygen. How to see oxygen deficiency using fetal heart rate monitoring? Let's have a simple understanding of this issue. I hope the following points will be helpful to everyone!

Reference chart of fetal heart rate monitoring for insufficient oxygen, how to see insufficient oxygen in fetal heart rate monitoring chart

There are two curves on the fetal heart rate monitoring chart, one records the changes in the fetal heart rate, and the other records the uterine contraction status. Under normal circumstances, the fetal heart rate is maintained at 120~160 beats/minute. The fetal heart rate is faster when the fetus is moving than when it is resting (at least 15 beats per minute), and it lasts for at least 15 seconds. This normal situation is called "fetal heart rate monitoring response type", which is the result that every expectant mother hopes to obtain.

If the fetal heart rate does not increase when the baby moves, or there is no fetal movement at all during the fetal heart monitoring period, this indicates that the fetal condition may be abnormal (such as lack of oxygen or embryo problems, etc.). This situation is called "unresponsive type" and the pregnant woman needs to do another fetal heart monitoring after 1 hour, or do other further examinations.

1. Fetal heart rate baseline (bpm): below 100 - 0 points, 100-119 - 1 point, 120-160 - 2 points, 160-180 - 1 point, above 180 - 0 points.

2. The genetic variation strength of fetal heart rate (bpm): below 5 means 0 points, 5 to 10 means 1 point, and above 10 means 2 points.

3. Fetal heart rate growth rate (bpm): less than 5 means 0 points, 5-10 means 1 point, and more than 10 means 2 points.

4. Repeated late-stage deceleration of fetal heart rate - 0 points, repeated genetic variation deceleration - 0 points, genetic variation deceleration - 1 point, no deceleration - 4 points, early deceleration - 4 points.

The total score of fetal heart monitoring can be obtained by summing up the scores of the above four items, and then compared according to the following index values: less than or equal to 4 is positive, 5-7 is abnormal, 8-10 is negative, and the fetal heart monitoring score is higher than or equal to 8 to be normal, preferably above 9.

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. Choosing microwave technology will not harm children. You only need to buy a fetal heartbeat monitor. Especially after 12 weeks of pregnancy, it is important to monitor the baby yourself. What’s interesting is that sometimes you can even hear the baby burping.

Fetal heart rate monitoring can often become one of the indispensable items in the examination of expectant mothers, because its function is irreplaceable. Fetal heart rate monitoring is an important test method to accurately assess the intrauterine condition of the fetus. It plays an important role in early detection of fetal heart rate abnormalities, proper treatment and reduction of perinatal mortality. If your baby is indeed found to have an abnormal fetal heartbeat, the fetal heartbeat graph on the monitor will immediately reflect the abnormality. After eliminating the common cause of fetal intrauterine hypoxia and the pregnant woman's own reasons, if the fetal heart rate continues to slow down, it is necessary to check whether the fetus is likely to have congenital heart disease.

After understanding the key functions of fetal heart rate monitoring, many mothers will no longer feel uneasy about various prenatal examinations. Fetal heart rate monitoring uses microwave technology, which is very safe for expectant mothers and fetuses. You only need to buy a fetal heart rate monitor to monitor your baby's growth and development anytime and anywhere. For the health of your baby, pregnant mothers please shoulder your responsibilities and go to the hospital for check-ups on time.
