When should you hear a fetal heart tone with a Doppler?
A fetal Doppler test normally takes place during your second trimester (weeks 13 to 28 of pregnancy). Some manufacturers of at-home fetal Dopplers say you may be able to hear your baby’s heartbeat as early as 8-12 weeks of pregnancy.
How do you check fetal heart tones with a Doppler?
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.
Can fetal Dopplers harm baby?
Using it for a few minutes once a week shouldn’t cause any harm to your baby. At-home fetal dopplers can also be potentially harmful because they can give you a false sense of reassurance, according to the United Kingdom’s National Health Service (NHS).
How many beats per minutes is a normal fetal heart tone?
The average fetal heart rate is between 110 and 160 beats per minute. It can vary by 5 to 25 beats per minute. The fetal heart rate may change as your baby responds to conditions in your uterus. An abnormal fetal heart rate may mean that your baby is not getting enough oxygen or that there are other problems.
How much is a fetal Doppler?
A pocket fetal Doppler can be found for as little as $40 at your local pharmacy. Many brands claim their dopplers work from 12 weeks on.
Why do I hear two heartbeats on my Doppler?
