What is Doppler Fetal Monitor?

Doppler Fetal Monitor or Doppler Fetal Heart Furek is a device commonly used during the prenatal tests to translate the sounds of the child's heart rhythm, albeit still in the uterus, to an audible level. The device uses the Doppler effect to create a simulation of audible heart rhythm. The use of the Doppler fetal monitor is a non -invasive diagnostic procedure used during routine prenatal care and is generally considered safe.

Doppler effect for the first time documented by Christian Doppler transfers changes in the frequency of the sound wave emitted by the source when moving in relation to the observer. The heart rate monitor with a fetal frequency Doppler detects high -frequency sound waves emitted when the child's heart beats. When you hear a heart rhythm with the doppler, it is not a real heart rhythm, but a representation. The use of this device is often referred to as doppler auscultation. This solution works as a conductor. The probe or converter is then traced back and forth over the abdomen, dockD is not successfully detected by a heart rhythm. Once the sound waves emitted by the heart of the fetus are detected to the monitor, where their sound is reinforced to the sound level.

There are benefits of the Doppler fetal monitor over a fetal stethoscope, which also detects the child's heart rhythm when it is in the uterus. Doppler fetal monitor allows all present in the room to hear the child's heart rhythm at the time of the examination. The fetal stethoscope provides only a person who wears headphones connected to the device, the opportunity to hear a fetal heart rhythm.

Doppler fetal monitors traditionally come in one of the two frequency levels, 2 or 3 MHz probes. Detect the heart rate of the fetus in the earliest weeks of pregnancy - from 8 to 10 weeks to the gestational period - equipment 2 MHz is usually a choice. For those women who have been decided to be overweight during pregnancy, the use of devices 3MHz suggests more often.

Many women decided to rent or buy Doppler monitors during pregnancy because they would like to have the opportunity to hear or check their child's heart rate at the moment. These models, which are created for home use, most often run on batteries. Some models created for home use are digital and offer added screen screen that shows the number of heart rhythms per minute.
