Many expectant mothers worry about their unborn baby during pregnancy. For these worried mothers, it can be very reassuring to buy a fetal doppler.

What is a Fetal Doppler? 
A Fetal Doppler is a device used to monitor a baby's heart rate throughout pregnancy. The device is non-invasive, which makes it a good safety choice for all pregnant mothers. The heart rate is measured by the doppler effect, emitting and receiving ultrasonic sound waves and monitoring the shift in pitch of the sound waves. Every returning sound wave is measured as the sound of the heartbeat heard through the speakers on the heart monitor. 

Ideal Times to Search for a Heartbeat 
An embryo's heart begins beating around 22 days after conception, but it takes much longer for doctors and parents to be able to listen to the heart beat. Between the 9th to 12th week of pregnancy, most fetal dopplers are able to pick up the sound of the heartbeat. Some heartbeats may be hard to find, and this is perfectly normal. Just be patient and try around more areas of the belly, eventually you will hear it! 

About the Angelsounds Doppler 
The Angelsounds JPD-100S Fetal Doppler is simple to use. The mother (or father) just press the probe of the device against the abdomen, put on the headphones and turn it on to hear the baby's heart beating. It comes equipped with headphones and a recording cable so that mothers can record the baby's heartbeat to a computer. 

Recording Sounds off the Doppler 
To record the baby's heartbeat, mothers can plug the recording cable into either of the headphone sockets on the doppler. The other end of the cable should be plugged into the microphone socket on a computer. Mothers can plug headphones into the other socket to listen to the heart beat as it's being recorded. Press the doppler probe against the abdomen and turn the Angelsounds device on. Using recording software on the computer, press the "Record" button, and the computer will begin recording the baby's heartbeat.
