Fetal doppler is a technology that has been used by medical professionals for over thirty years to monitor fetal heart rate. Fetal heart rate is a strong indicator of the health of an unborn baby. A heart rate within the average 110-160 beats per minute indicates that adequate amounts of blood and oxygen are reaching the babys heart.
Fetal doppler is one of several methods of measuring fetal heart rate. When the doppler device is used, low frequency sound waves are conducted by a gel medium through the skin and tissue of the mothers abdomen. When the sound waves encounter sound inside the womb, such as the babys heartbeat, they bounce back to the monitor and are translated into sounds that can be heard by physicians and parents.
Fetal Doppler Is Safe to Use
Use of fetal doppler is regulated by the FDA, which has approved it for home use. There have also been many studies done to assess its safety. No study has yet found any adverse effects from the regular use of fetal doppler. In fact, the peace of mind that comes with knowing that your unborn child is healthy and happy has been deemed such a large benefit that in-home monitoring of fetal heart rates has significantly increased in recent years.
Because of the upsurge in popularity of fetal heart rate monitoring, there are now many businesses and websites which offer sale or rental of doppler devices. These models have been designed for ease of use and clear, consistent readings. Most models are handheld and can be operated by one person, and because of new advances in doppler technology, finding your babys heartbeat has never been easier. While ease of use and peace of mind are very important, many parents say that being able to share the joy of listening to your unborn childs heartbeat with friends and loved ones is the biggest benefit of all.
A baby heartbeat is something that all mothers look forward to hearing as they move through the stages of pregnancy. In every fetus, a primitive heart begins beating around the sixth week of pregnancy, but a babys heartbeat is not detectable until around week twelve. Once the twelfth week mark is reached, a doctor will begin to monitor the unborn babys heart rate as a way to ensure she continues to be healthy.
Analyzing a Baby Heartbeat
The rate of the baby heartbeat indicates whether or not the childs heart is receiving an adequate flow of blood and oxygen. The average fetal heart rate is 140 beats per minute, but anywhere between 110 and 160 beats per minute is considered normal. An above or below average heart rate does not necessarily mean that there is something wrong with the fetus; other tests are needed to confirm that. However, an abnormal baby heartbeat can be an early warning sign of problems to come, giving physicians a head start to help ensure the health of the baby.
Physicians have a number of ways to monitor the heart rate of an unborn fetus. One of the most popular of these options is the doppler ultrasound. Doppler ultrasounds send low-level sound waves through the skin and tissue of the mothers abdomen, toward the uterus. When these sound waves encounter other sounds in the womb, the babys heartbeat, for example, they bounce back to the monitor and are translated into an audible heartbeat sound.
Many mothers-to-be find listening to their childs heartbeat to be an immensely comforting and even blissful experience. For this reason, there has been steadily increasing demand for a home doppler system from women to listen to their childs heartbeat at any time, not just when they are at their doctors office. Many businesses are now offering easy to use, low cost doppler ultrasounds that can be used effectively at home, providing many women with the peace of mind that comes from knowing their unborn babies are healthy and happy.
Fetal heartbeat begins around the sixth week of pregnancy, but at this stage in a pregnancy the heart is too small to be heard, even with amplification. Week twelve is generally accepted as the time when a babys heartbeat becomes audible, although even then it may be difficult to locate. Finding the fetal heartbeat is dependent on the position of the mothers uterus, whether the mother is slender or heavy, and the position of the baby in the womb (it is easier to hear a babys heartbeat from the back rather than the front).
It is a common misconception that a slower than average fetal heart rate means a woman is carrying a boy, while a quicker than average rate means she will have a girl. There is no evidence to support this theory, however, just as there is no evidence that shows that an unusually loud or quiet heartbeat means anything, good or bad. One thing that is agreed upon, however, is that hearing your babys heartbeat for the first time is an exciting and joyful experience, something to which all parents-to-be look forward.
More on Fetal Heartbeats
Physicians have a number of tools at their disposal to detect fetal heartbeat. Of these, one of the most often used is the doppler ultrasound, which sends harmless sound waves at the heart of the fetus. The beating fetal heart affects the return path of these sound waves. The instrument then translates this disturbance into a heartbeat sound that physicians and parents can hear.
When the rate of a babys heartbeat falls into the normal range (110 to 160 beats per minute) it indicates that adequate amounts of blood and oxygen are reaching the babys heart, which in turn spreads them to the rest of the babys body. Doctors continue to monitor the heart rate of a fetus throughout a pregnancy in order to ensure its continued health. While an abnormal heart rate does not necessarily indicate a serious problem, it can be an early warning sign, allowing doctors to catch any abnormality before it becomes too serious.
Doppler ultrasound is based on the principle of the Doppler effect. It is often used to monitor the health of a fetus because it can not only provide a picture of the unborn child, it can also monitor the childs heart rate and serve as an early warning system to detect any fetal abnormalities.
During an ultrasound, low-level sound waves are sent through the mothers abdomen toward the fetus. Any movement that these waves encounter change their frequency; the frequency becomes higher if the object they reflect from (the fetus) is moving toward them, and lower if the object is moving away from them. The ultrasound machine translates these changes in frequency into sounds or pictures that provide valuable information about the health of the baby.
By monitoring fetal heart rate and providing physicians with a clear picture of the fetus and the womb, doppler ultrasound is an invaluable tool in determining the health of a pregnancy. Ultrasounds are most often used for the following reasons: confirmation of pregnancy, detection of vaginal bleeding early in a pregnancy, measuring the age and size of a fetus, early detection of fetal malformation, determining whether the placenta is situated correctly, detection of multiple pregnancies, and measuring the amount of amniotic fluid present in the womb.
There have been numerous advances in doppler ultrasound in recent years. Color flow mapping allows physicians to monitor fetal blood flow in real time, with different colors corresponding to different directions of blood flow. While traditional ultrasounds offer blurry and sometimes indeterminate pictures of the fetus, the new 3-D and 4-D ultrasounds show parents much more lifelike renderings of their babies, even allowing them to watch their babys movements and facial expressions. These new ultrascans not only provide parents with an opportunity to get to know their child sooner, they also help physicians detect anomalies like cleft palate and spina bifida much earlier than ever before.
Benefits of Using a Home Doppler Ultrasound
The peace of mind that seeing and hearing their unborn child provides to parents has caused a recent trend toward providing doppler ultrasounds tailored for in-home use. Many businesses are now offering hand-held models that can be used easily and accurately anytime. Many parents describe hearing their babys heartbeat as a joyful and reassuring experience; the in-home models allow them not only the security of being able to monitor their child on their own, they also allow them to share their joy and excitement with loved ones.
Dopplers are ultrasound scans used to monitor the health of a fetus during the last six months of pregnancy. Dopplers aim harmless low-level sound waves at the fetus through the skin and tissue of the mothers abdomen, via a conductive gel. The paths of these sound waves are disturbed by the movements of the baby and are bounced back to the monitor. These disturbances are then translated into an audible heartbeat or visual picture which physicians use to determine the health of the fetus.
When reading the fetal heartbeat provided by dopplers, physicians are checking to be sure the heart rate falls within the average 110 to 160 beats per minute, indicating that adequate blood and oxygen are reaching the heart. If the heart rate falls outside of that range, it does not necessarily mean there is a serious problem; however, it may point out potential health risks to the fetus.
Medical Benefits of Dopplers
The visual ultrasounds provided by dopplers allow physicians to check for things like early vaginal bleeding, fetal malformation, problems with placental location, and multiple pregnancies. New 3-D and 4-D ultrascans, which provide a much more lifelike and easy to read picture of the fetus, allow doctors to detect problems like spina bifida and cleft palate earlier and more easily.
While all of this information is very helpful to physicians, it also provides parents-to-be their first contact with their unborn child. Many mothers describe their first time hearing and seeing the baby as a blissful experience during which they form a strong bond with their baby. Regular ultrasounds also provide parents with a feeling of security, knowing that their babys health is being effectively monitored and watched over.
