【Q&A】

When can I hear the fetal heartbeat?

The fetal heartbeat starts forming at 8 weeks and can be detected using a medical device

Some mothers might be able to hear it at 10 weeks, and the majority at 12 weeks

Most mothers can hear it at 16 weeks,and at 28 weeks when the fetus has fully developed,you can increase the monitoring time

Does the probe show values when it touches the arm or other areas?

When the device is turned on,the probe may sense air movement,and when it touches the arm or thigh,it may generate interference signals

This can cause the speaker to emit interference noise and numbers

The device cant distinguish between interference signals and fetal heart signals at this point

Its recommended to use the suggested detection positions or follow the doctors instructions for placing the probe,then slowly move it to search carefully after finding the fetal heart position

After accurately locating the fetal heart,avoid moving the probe,and after about 5 seconds,when the signal stabilizes,the fetal heart rate reading will be accurate

What if I cant find the fetal heartbeat?

Some first-time pregnant mothers may have difficulty finding or locating the fetal heartbeat

It could be due to the pregnancy being at an early stage

Make sure there is enough coupling agent applied to the probe,and patiently search for the optimal measurement position

Practice will make it easier over time

During early pregnancy (14-24 weeks),the fetal heart is often found along the midline just below the navel or on either side

As the fetus grows,the fetal hearts location will also move upward

In mid-pregnancy (24-32 weeks),the fetal heart is generally found on the left side of the navel,and on the right side if you feel frequent fetal movements on the left

In late pregnancy (32-40 weeks),the fetal heart sound is transmitted from the babys shoulder blades and is clearest when heard on the mothers abdominal wall,near the babys back

Why is there noise during use?

Home fetal heart monitors use the Doppler principle,which amplifies and spreads any vibrations to hear the babys faint heartbeat

When the device is turned on,the probe may sense air movement and generate some noise,especially when its in contact with the skin and producing more significant vibrations,which may result in some noise

The fetal heart monitor can also pick up sounds like intestinal movement

Using a coupling agent can significantly reduce air interference,and once youve found the fetal heart position,it will become clear

When is the best time to measure,and how often per week?

Its recommended to monitor three times a day—within 30 minutes after waking up,within 60 minutes after lunch,and 30 minutes before bedtime,each time for 1-3 minutes

For pregnant women after 28 weeks,when the fetus is fully developed,you can increase the monitoring time and frequency

How do you measure for twins? Is it more challenging?

Typically,youll need two fetal heart monitors with different probe frequencies,one using 2MHz and the other using 3MHz. This will prevent interference

Its challenging to distinguish between twin heart rates,so its best to consult a doctor for guidance

Can I use the device without coupling agent?

You can use water,olive oil,edible oil,or baby oil as substitutes to prevent air interference and reduce noise

Will daily monitoring have any negative impact on the fetus?

Regular monitoring is not harmful

The ultrasound intensity of qualified products is far below the national limits
