How often is it appropriate to monitor the heart rate and how long does it take

Fetal heart rate monitoring is done at the earliest from 28 weeks, and then pregnant women go to the hospital once a week, which can reduce fetal brain mortality to a certain extent, and is still very useful, so pregnant women must do fetal heart rate monitoring in time, and the data is effective in about 20 minutes each time, if you want to understand the fetal situation more comprehensively and in real time, you can choose to use fetal heart rate monitoring at home.

Fetal heart rate monitoring takes about 20 to 30 minutes.

Under normal circumstances, fetal heart rate monitoring generally lasts for about 20 to 30 minutes, and whether there is hypoxia or abnormality is judged according to the situation of fetal heart rate monitoring. If fetal heart rate monitoring passes, then only this one time is required; If fetal heart rate monitoring reflects intrauterine hypoxia or poor fetal heart rate response, then continuous fetal heart rate monitoring is required, which can continue for half an hour or an hour.

If the pregnant woman feels that the fetal movement is frequent or reduced, it may be a manifestation of fetal hypoxia, and she can not be careless, and she needs to review the fetal heart rate monitoring and color ultrasound at any time, and it is necessary to judge whether oxygen inhalation and other special ** are needed according to the situation.

What do I need to pay attention to when monitoring the fetal heartbeat?

Before the test

1.Because the fetal heart rate monitoring is relatively long, eat and empty the bladder an hour before the examination.

2.Avoid mood swings.

2.If there is no change in the fetal heart rate for more than 20 minutes, the doctor may ask the woman to pat her tummy and talk to the baby or eat some food to see if there is any change in the heart rate.

After the check

1.After the examination, the fetal heart rate is found to be too fast or too slow, and the doctor's professional judgment is required to determine the next step.

2.If the fetal heart rate is found to be substandard, the pregnant woman may need to be hospitalized for further ** including fetal biophysical evaluation, ultrasound, etc.

Fetal heart rate monitoring is a test that checks the heartbeat of the baby in the mother's womb. So many people wonder, how many weeks does fetal heart rate monitoring start? Approximately, how many weeks does fetal heart rate monitoring begin? How long does it take to monitor a fetal heart rate?

How many weeks does fetal heart rate monitoring start?

In general, self-monitoring is not allowed before 15 weeks of pregnancy. For pregnant women at 15-28 weeks of pregnancy, it is safe to take the test three times a day for one minute each. For women after 28 weeks' gestation, the fetus is sufficiently differentiated to prolong the duration and frequency of monitoring.

For high-risk pregnant women after 35 weeks of gestation (e.g., pregnant women with gestational hypertension, hyperthyroidism, etc. In the hospital, the fetal heart rate should be continuously monitored with a fetal heart monitor, and if necessary, it can be continuously monitored for a long time (more than 1 hour).

How long does it take to monitor a fetal heart rate?

During the prenatal check-up, the fetal heart rate monitoring time is about 20 minutes. The monitoring of the fetal heart rate is continuous and uninterrupted. If any anomalies are found, the monitoring time will be extended.

For high-risk pregnant women, after 35 weeks of pregnancy, hospitalization is required to monitor the fetal heart rate. If necessary, each monitoring will last more than 1 hour.

Moms who need fetal heart rate monitoring

1.Have diabetes mellitus and are receiving insulin**. During pregnancy, high blood pressure or other medical conditions can affect your health.

2.The fetus is small or does not develop properly.

6.It's past your due date and the doctor wants to see how the baby in your belly is doing.

What about the fetal heart rate monitoring chart?

There will be two curves on the fetal heart rate graph, one that records changes in the fetal heart rate and the other that records contractions. Normally, the fetal heart rate will remain at 120 to 160 minutes, and the fetal heart rate will be faster than at rest (at least 15 minutes faster) and last at least 15 seconds. This normal condition is called "fetal heart rate monitoring response" and is common to every pregnant mother.

If the fetal heart rate does not increase when the fetus is moving, or if there is no fetal movement at all during fetal heart rate monitoring, there may be an abnormality in the fetus (such as a lack of oxygen or placental problems). ), which is also known as the "non-reactive type". Pregnant women need to have fetal heart rate monitoring or other further tests again after 1 hour.

When pregnant women have a prenatal fetal heart rate check-up, there will be a set of special scoring criteria, with a total score of 10 points. A score above 8 is normal, and a score below 8 requires further observation and diagnosis.

In the case of a normal pregnancy, fetal heart rate monitoring will be added to every prenatal examination from the 32nd week of pregnancy, and fetal heart rate monitoring will be done once a week from the 37th week of pregnancy.

If the pregnancy is at high risk or has comorbidities or complications, such as pregnancy-induced hypertension, post-term pregnancy, diabetes mellitus and pregnancy, this test may be performed from 28 weeks of pregnancy.

Fetal heart rate monitoring can be done after the baby is about 34 weeks, once every two weeks after 34 weeks, and once a week after 37 weeks.

Generally, fetal heart rate monitoring can be done after 34 weeks, normally once every two weeks, and once a week after 37 weeks.

Fetal heart rate monitoring is started at 34 weeks.

Fetal heart rate monitoring is usually done at 34 weeks in pregnant women without high-risk factors, and may need to be earlier when high-risk factors are present. However, if there are high-risk factors, such as gestational hypertension, intrahepatic cholestasis during pregnancy, threatened preterm birth, etc., it can be advanced to 32 weeks, or even 28 weeks, to understand the intrauterine situation of the fetus and ensure the safety of the fetus.

Fetal heart rate monitoring can continuously monitor the dynamic changes of fetal heart rate, and can also record uterine contraction and fetal movement, according to the fetal heart rate monitoring, can judge the intrauterine situation of the fetus and evaluate the function of the placenta, is an indispensable means of obstetrics.

What is fetal heart rate monitoring?

Fetal heart rate monitoring is the abbreviation of fetal electronic monitoring, which refers to a method taken in the third trimester of pregnancy to understand whether the fetus has abnormal conditions such as hypoxia in the uterus. It can continuously observe and record the changes in fetal heart rate, and trace the uterine contraction and fetal movement, reflecting the relationship between the three, such as whether the fetal heart rate accelerates after fetal movement, whether the fetal heart rate slows down after uterine contractions, etc.

The purpose of fetal heart rate monitoring is to detect adverse conditions in time and assist clinicians in making reasonable diagnosis and treatment plans. Fetal heart rate monitoring can find out if the fetus has symptoms such as hypoxia and irregular heartbeat.

Fetal heart rate monitoring is not good for the fetus, before doing fetal heart rate monitoring, some problems should be noted, such as pregnant women can not take some drugs that affect the monitoring results; Pregnant women should maintain a calm mind and not be too nervous.
