Sonoline A model is for simple auscultation. Sonoline B model is a high performance model with (fetal heart rate) LCD digital display. It has 3 work modes: real-time FHR display mode, averaged FHR display mode, and manual mode. They are all availabe for user replaceable batteries.
What is the best MHz for fetal Doppler?
A 3-MHz probe is recommended to detect a heart rate in early pregnancy (8–10 weeks gestation). A 2-MHz probe is recommended for pregnant women who are overweight.
What is the whooshing sound on Doppler?
Likely Causes: This “whooshing” sound is blood flow in the placenta, which is perfectly normal! Solution: Reposition the monitor to capture the fetal heart rhythm instead. Likely Causes: The fetus has “kicked” or “punched” the doppler. This is perfectly normal.
How do you use Angelsounds Doppler?
Listening to the heartbeat is easy: Place the probe on your belly and move it slowly back and forth until you hear the heartbeat clearly. Sometimes you might need to hold the probe at a slight angle to receive a better signal.

Can I use my Doppler everyday?
Is it safe? As long as you don’t use a fetal doppler too often, the device should be perfectly safe. Limit your use to once every other day for about 5 minutes.
Can you overuse a fetal Doppler?
There is no evidence that at-home fetal Dopplers are harmful. However, the heat that they generate can pose a risk to the baby, so it is reasonable to assume that overusing them can cause a problem.
Can Doppler cause miscarriage?
There is no evidence of immediate or long-term harm to the developing fetus from exposure to B mode ultrasound. However, exposure to high levels of Doppler ultrasound during early development is increasingly common, and the full safety implications of this exposure are not clear.
Can you use a Doppler without gel?
You’ll also need some ultrasound gel – a simple solution that acts as a lubricant and helps seal the bond between the doppler device and the womb, whilst making the precise detection of a heartbeat easier. Tip 2: Make sure you’re comfortable.
What are the risks of Doppler ultrasound in pregnancy?
Some studies have reported effects of exposure to diagnostic ultrasound during pregnancy, such as low birth weight, delayed speech, dyslexia, and non–right-handedness. Other studies have not demonstrated such effects.
Is Doppler ultrasound safe?
No injurious effects have been identified from ultrasound scanning of the fetus. However, changes in power output, increased use of Doppler ultrasound and a change in regulations governing outputs means that every measure should be taken by users to maintain safe practices.
Where should the Doppler be placed at 10 weeks?
Place a small amount of gel (Doppler gel only) on the probe at the end of the monitor. Then put the probe on your lower abdomen, near your pubic bone. Angle or tilt the probe, keeping contact between your skin and the probe at all times, until you hear a galloping sound — the fetal heart rate.
Why can’t I hear my baby’s heartbeat with a Doppler at 14 weeks?
There are other reasons for not hearing a heartbeat with a baby Doppler, too. These include gestational age, position of the placenta, position of the uterus, and potential pregnancy loss.
Why can’t I hear my baby’s heartbeat with a Doppler at 12 weeks?
Couldn’t find heartbeat on doppler at 12 weeks
If you’re 10 or 11 weeks pregnant, it’s very likely you won’t hear your baby’s heartbeat for a while yet. Before 12 weeks, your uterus is still small and tucked behind the pubic bone. This means it can get in the way of finding the right position to place the baby doppler.

Your Body at 12 Weeks of Pregnancy
Your uterus is the size of a grapefruit and completely fills the pelvis. It rises up into the area of the abdomen, as shown in the image. The fundus, the upper end of the uterus, is just above the top of the symphysis where the pubic bones join together.
