The gelled probe is moved further around the pregnant woman’s abdomen until it detects the sound of the fetal. These sounds are audible through the speaker, which is present on the central unit. Also, it displays the heartbeat in numbers on the main unit.

The heart rate of a baby may fall between 110 and 160 beats per minute. It is essential to check the fetal heart rate during labor, which can change in response to contractions or any activity. An abnormal heart rate of the baby indicates that the fetus is not getting enough oxygen or having any other problems, in such cases it is suggested to take advice from doctor.

Fetal heartbeats can be detected by the fetal Doppler around 10 to 12 weeks of the pregnancy time. Depending on the various body conditions, it may be different so that the detection can happen slightly earlier or later. There are multiple reasons that the fetal heart rates may not be detected, which are as follow:

•Your pregnancy due date is miscalculated.

•When you have a tilted uterus, it is more difficult to hear your baby’s heartbeat.

•The layers of fat present on your abdominal act as a barrier and cannot listen to the sound.


The baby’s heartbeat will also be monitored during labor time. Frequent monitoring with the help of the fetal Doppler is usually done every 15 to 30 minutes a day during the first stage of the labor and 5 to 15 minutes a day during the second stage. These can also be consulted with the doctor for better advice based on the labor conditions.
