If you are worried there is something wrong with your baby, go to the doctor just in case. Maybe the fetal doppler will give you some peace of mind. Perhaps you know that you will end up going to the doctor’s every day because you are a natural worrier. Many parents worry that their child is unhealthy when everything is perfectly normal. It can only tell you if their heart is beating, and only if it is not picking up on the sounds your own body is making. Again, the fetal doppler cannot tell you if your baby is healthy. If you have preexisting health conditions, you will want the added peace of mind a fetal doppler brings. Just because you can hear the baby’s heartbeat doesn’t mean it is healthy. If a baby has been moving often and slows down, it is a signal to seek medical help. Health professionals claim that a change in the movement of the baby is the most important thing to look out for. Nurses are trained to differentiate between the sounds your body is making and the sound your baby is making. Unfortunately, fetal dopplers will often pick up on the mother’s heartbeat. A fetal doppler can be used before the baby starts kicking to show it is alive. You may have already experienced problems with the health of your baby in the past.
However, there are several reasons why a parent may choose to buy a fetal doppler. If you feel that something is wrong, even with a healthy heartbeat, you should visit your doctor straight away. It is not a replacement for medical care. Fetal dopplers give you an added peace of mind. It is natural for any parent to worry about the health of their baby. Some devices also offer a visual representation of the heartbeat. The doppler effect is used to create an audible duplicate of the baby's heartbeat. When sound waves move closer to an observer, they get compressed, which in turn means they become a higher frequency. The doppler effect is a change in sound by either increasing or decreasing frequency. What is a Fetal Doppler?Ī fetal doppler is a hand-held ultrasound sensor used to detect the heartbeat of an unborn baby. What should you consider when choosing the right fetal doppler for you? Check out our buying guide for some handy tips and advice. It is amazing that you can now get this technology for your home. Fetal dopplers also allow your other children to see the baby as a being rather than some abstract idea which they may struggle to grasp. They allow a level of reassurance that the baby is doing fine, allowing you to feel closer to your little one. Also, each of the Emory ED machines uses the general concepts described above, but may have subtle differences or other variations of doing the same thing – but all involve M-mode, not pulse wave Doppler.Fetal dopplers have become all the rage between new parents and seasoned parents alike. Note: the above does depend on a fetus remaining rather still while the M-mode cursor is on.

A software calculation will turn this measurement into a calculated fetal heart rate that you can then document (Image 2). This is done by measuring from peak-to-peak (or valley to valley) of two subsequent waves. By pressing the freeze button, one can then use the caliper function to measure the fetal heart rate. The waveform represents the movement of the beating heart. Generally one is able to see a faint sinusoidal wave across the M-Mode screen. The resulting image is a representation of the movement as seen through the single M-mode cursor beam. Using the trackpad or mouse ball, place the beam over the best view of the beating heart. In actual bedside practice, first visualize the beating fetal heart on the screen (with trans-abdominal or transvaginal scanning, with preset changed to OB setting), then press M-Mode this brings up a single M-Mode cursor beam. In brief, M-Mode gives a real-time representation of a moving object. When visualizing a developing pregnancy, think of using “ Mommy-Mode.” This is an easy way to recall the need for M-Mode imaging. Particularly, investigations with laboratory animals have documented that pulsed (Doppler) ultrasound can cause elevations in temperature and damage biological tissues in vivo. Although not studied well in humans, inadvertent and prolonged use of pulse-wave Doppler may have adverse effects on the unborn fetus. This is a rather easy US skill to acquire, but the measurement must be done with the M-Mode, not pulse wave Doppler: see Image #1 – incorrect use of Doppler and image #2 – correct use of M-Mode. As commonly practiced, the pregnant patient has an additional vital sign – assessment of the fetal heart rate. The image of the week focuses on fetal heart rate determination.
