It’s important to consider the duration for which a Fetal Doppler is used during pregnancy, as this can be a key aspect of antenatal or prenatal care.
In physics, according to Christian Doppler (29 November 1803 – 17 March 1853) was a physicist and mathematician from Austria. Doppler is best known for his contribution to establishing principles about a phenomenon called the Doppler Effect.
The Doppler effect is widely used in the medical field, including measuring the speed of blood flow in blood vessels using ultrasonic waves. Another use of the Doppler effect in the medical field is that it is used to detect the fetal heartbeat in the womb using ultrasonic waves. The tool is compact and portable, known to the public as Fetal Doppler.
Other benefits of the Doppler Effect in the medical field, see here!
Fetal Doppler is a diagnostic tool used to detect a baby’s heartbeat using the principle of electromagnetic wave reflection. This tool is very useful for determining the health condition of the fetus, and is safe to use and is non-invasive.
The Fetal Doppler tool is used to detect and display the heartbeat of the fetus in the womb, so the accuracy and safety factors of the tool are needed in accordance with the desired provisions. Medical devices that are in direct contact with humans and are very critical (related to life) must be calibrated to ensure the correct output value and safety of the user. The accuracy of an instrument arises from correct calibration, meaning that the measurement results can be traced back to national or international standards, on this basis it is necessary to calibrate the fetal Doppler instrument in accordance with the provisions that have been scheduled.
Fetal Doppler is generally used in the second and third trimesters of pregnancy after the fetal heartbeat can be heard clearly. This tool is usually used by medical personnel such as doctors or midwives. The first fetal heartbeat appears 22-23 days after fertilization, namely in the middle of the fifth week. However, the fetal heartbeat can usually begin to be heard with fetal Doppler at 10 to 12 weeks of gestation.
The fetal heart actually starts beating around the sixth week of pregnancy. However, the pulse was still too weak to be detected by medical equipment. As gestational age increases, the fetus’ heart continues to grow and develop. The fetal heartbeat becomes stronger over time until it can finally be heard.
It works by emitting ultrasonic waves into the body, then they are received back by the sensor in the device and converted into sound. This sound will provide information about the fetus’ heartbeat and help the doctor or midwife monitor the health of the fetus during pregnancy.
Normally, the fetus’s heart rate starts beating when it is 6 weeks old and the number of heartbeats will increase as the gestational age increases. At 6 weeks of age, the normal heart rate is 90 to 110 beats per minute (bpm). entering 9 weeks and above increases between 120 and 160 bpm.
If the heart rate is less than 90 bpm at between 5 and 8 weeks of gestation, then this condition has a high risk of miscarriage. The mother must consume nutritious food so that the fetus’s nutritional needs can be met.
How to hear the fetal heartbeat
Obstetric ultrasound or sonogram is the most accurate method and is often used by your doctor or midwife to check the baby’s heartbeat.
Apart from checking the heartbeat, the obstetrician can also use ultrasound to confirm the following things:
- Pregnancy at six weeks
- Determine the age and size of the fetus
- Rule out problems with pregnancy
- Checking the possibility of twin pregnancy
You may be able to hear the fetus’ first heartbeat via fetal doppler at your routine consultation visit.
Your doctor or midwife may be able to detect the baby’s heartbeat using Doppler at 10 weeks of pregnancy, but the fetus’s heartbeat is more often heard at 12 weeks.
Whether you can hear the fetus’ first heart sound will depend greatly on your body size, the position of the uterus, the location of the baby, and the accuracy of the gestational age.
These are the various things you need to know about fetal heart rate. If you can’t hear your baby’s heartbeat, there’s no need to panic. This is a fairly common occurrence and has various reasons behind it, such as the age of the fetus, location of the baby, position of the uterus and accuracy of gestational age.
It is important to know that the use of the fetal Doppler device must be known or recommended by a doctor or midwife. Because, there are some things that do have terms and conditions for use.
