A fetal doppler 

A Fetal Doppler is a test that uses sound waves able to check the baby’s heartbeat. This is a type of pregnancy doppler ultrasound that uses a handheld device to observe the changes in movements that are translated into sound waves. 

Early Stages to check fetal doppler test works? 

Most pregnant ladies can hear their baby’s heartbeat during the normal routine checkup by using the fetal doppler. Also, many ultrasound machines allow hearing the heartbeat of the baby’s before hearing that is used with the fetal doppler. Most of the women get the ultrasound before the 12 weeks.

A fetal doppler test usually takes during the second trimester ( from 13 to 28 weeks of the pregnancy) and some manufacturers dopplers machines say you can hear at home a baby’s heartbeat as soon as 8 to 12 weeks of pregnancy. But the expert’s sonographers say; the right time to hear the baby’s heartbeat is after 13 weeks. The reason behind this is that the womb is in your pelvis at the time of the first trimester. That’s why the device didn’t work correctly. 

Some at-home usable devices are not to be used before the 16 weeks. 

If you want to try to hear your baby’s heartbeat. It is good to be concerned with your doctor first and take first your prenatal checkups. If you are pregnant less than 12 weeks and planning to buy home fetal doppler to avoid unnecessary concern. Talk about the device and know all the benefits and risks involved in this device before moving forward with it. 

Fetal doppler test at the clinic 

Go to the clinic, you will lie down and the physician will hold the small probe against your abdomen that makes the sound waves. The sound is sent back to an amplifier, where you can hear that the procedure will be safe and painless. 

Fetal doppler test at-home 

Using a fetal doppler device without an expert guide not to be safe for the mother. Before, using a fetal doppler at home you should check all the instructions and must watch the tutorials videos available with all the instructions. Doing at home is not as smooth as doing it by a physician at the clinic. 

Fetal monitoring 

In pregnancy and during labor, your doctor asked to check the health of your unborn baby (fetus). This can be done by checking the baby’s heartbeat and other functions.

Fetal monitoring is a general procedure. 

Monitoring can be done in two ways; 

It can be done internally directly on the baby inside your uterus ( internal monitoring) and it can be done externally outside of your abdomen ( external monitoring). 

Difference between external and internal monitoring 

External monitoring

This monitoring is done by a special tool called a fetoscope, which is a stethoscope that has a different shape and can also be done by using Doppler. This is an electronic device that uses sound waves and a computer. 

Internal monitoring

A small wire electrode is put on your baby’s head when your baby is inside your uterus. 

Fetal heart rate monitoring is used to check the rate and rhythm of the heartbeat. It checks how much a baby’s heartbeat increases or decreases. The medium fetal monitoring heart rate should be 110 and 160 beats per minute. The fetus heart rate can be changed and the baby responds to conditions in the uterus. An abnormal fetus shows the baby is not getting enough oxygen and has problems in other functions. An abnormal pattern means emergency cesarean section ( C – section) delivery is needed. 

Why? I need fetal monitoring 

Using a handheld device and doing fetal monitoring is a common basic type of monitoring, this can be often done during prenatal checkups. Fetal monitoring helps the problems in the baby during the time of late pregnancy and labor. If it can show the other testing or C-section delivery is needed.

Things to consider before buying fetal doppler

Fetal monitoring and dopplers is a vital tool to measure fetal health. Monitoring is a key to reducing intrapartum stillbirths. Fetal monitoring can occur in a variety of ways, but stillbirths most devices are still prohibitively expensive for low-resource settings.

Without any technician guidance, you are not able to use this device and it can be harmful to your baby during pregnancy. 

Before, purchase any doppler device you first ask and take advice from your doctor. Your doctor will give an utter recommendation and tell you about the usage in the right way. Apart from that, before purchasing any fetal device you just need to check out the functions, quality, screen, sound quality of the device. And also should check the reviews as well.

Final thoughts

Fetal doppler/ Fetal monitoring is the safest way to check your baby’s heart rate condition and other functions. This device checks your baby’s condition inside as well as outside the abdomen and if any problem may happen, tracks the condition during the pregnancy but this device you can not use by yourself. You need to use it under doctor consultation. 

Frequently Asked Questions:

  1. Can I get out of the bed with a fetal monitor?

yes, you can get out of bed with a fetal monitor or can sit on a chair or also, stand near the monitor. But you can’t walk around and take a bath. Sometimes you can check the baby’s heartbeat without wires.

2. What is the most accurate procedure for monitoring normal pregnancy?

Auscultation is commonly considered or an acceptable form of monitoring if your pregnancy is at low risk.

3. Who needs continuously fetal monitoring?

Most experts recommended continuous EFM for those people in labor who have the prior Cesarean. This is due to the most common sign of uterine rupture being fetal heart rate abnormalities. Abnormal heart rate patterns occur with 70% of uterine ruptures.

4. When can I stop fetal monitoring?

Fetal is before Cesarean birth, women requiring Cesarean birth fetal surveillance should continue unless abdominal sterile preparation has begun; if internal fetal monitoring is in use; it should continue until the abdominal sterile preparation is done.

5. Is external monitoring safe?

There is no physical risk, fetal monitoring risk with the auscultation or external fetal monitoring. On the other hand, an internal fetal monitor carries a little risk of infection. it invades the uterus.

6. What is mobile fetal monitoring?

during, labor your doctor and nurse will check your baby’s heart rate to track the whole procedure how is the baby doing and tolerating the contractions. The electric monitor is used to detect the signs of the fetal distress.

7. Baby monitoring during C-section?

Fetal monitoring is important during the C-section while the mother has been giving the general anaesthesia reason, the anaesthesia can negatively impact the fetus the risk is higher infants who have exhibited signs of fetal distress before the surgery.

8. How? Accurate the fetal monitoring

Results: The positive percentage agreement was 81.7 and 73% of the abdominal fetal ECG and ultrasound. The abdominal fetal ECG has a lower root mean square error (5.2 vs. 10.6 bpm, p < 0.001) ultrasound.

9. How does wireless monitor works?

Here is an electronic device called a transducer attached to the wide, stretch bands that will be placed around the belly. This device can monitor your baby’s heartbeat. Another device can track your contractions that are usually attached to the second band around your belly.

10. When you have to start CTG monitoring?

The continuous CTG monitoring should be started in the first stage of labor and during the expulsion stage, however high risk in pregnancy.
