Essentiality of Fetal Domestic Monitor
Modem medicine think that:
FHR is an important gist to identify fetal health, by recording FHR changes
can observe fetal hypoxia, fetal distress and the umbilical cord around the neck,
and other symptoms. Fetal domestic monitor test FHR rate changes by listening
to fetal heart sound mainly. Fetal domestic monitor is a powerful guarantee to
improve generational safety. Fetal heart rate changes most obviously in the
following three periods:
• Within 30 minutes after pregnant women get up
• Within 60 minutes after pregnant women finish lunch
• Within 30 minutes before pregnant women go to bed
For the above three periods, because of the change of the body statua
of pregnant women, the activity of food digesting needs the body to provide
more oxygen, relatively, the oxygen for fetus become less. It is easy to arose
symptoms such as fetus anoxia. Testing the FHR at this time can display
the healthy statua for the fetus best.
The above three periods can only be tested at home by pregnant women
themselves, so FHR domestic monitor is very important. We advise the pregnant
women tu measure every day respectively at early, middle and late time, every
time measuring the fetal heart rate and listening to the fetal heart rate for about
one minute, and recording the measurement results for the medicai reference
when go tu the hospital.
Generally, the medicine deems the normal fetal heart rate as: 120BPM~160BPM;
slightly too fast: 161BPM~180BPM; heavily too fast: above 181BPM; slightly too
slow: 119BPM~100BPM; heavily too slow: below 99BPM.
This device can hear the fetal heart sound for fetus above twelve weeks,
and check the LCD display. Finding too fast or too slow should go to hospital
for further checks to ensure safety.
