What is a prenatal doppler?
Prenatal doppler is a device used to listen to the heart of the developing fetus inside the uterus of a pregnant woman. It uses an ultrasonic converter and a doppler effect to create an audible representation of a fetal heart rhythm. Some models can also calculate the heart rate and record the sound of the heart rhythm. Prenatal doppler is easy to use and does not pose any risk to the developing child. Although commonly used in the doctor's office for prenatal care, some expectant mothers rent or buy their own for home use. One part is the ultrasonic converter, which is used as a probe to find a heart rhythm. Often it has a cylindrical shape with an extended flat end and radiates and receives sound waves. The second part is the receiver and the control unit, which is usually a box with several buttons that control the unit, speaker; Sometimes it has a heart rate.
Prenatal Doppler works in a different way than an acoustic fetal stethoscope. The ultrasonic converter is used as a probe to find a heart rhythm with sound waves that reflect back. This reflection of the sound waves that provides information about the sound or object is called the Doppler effect. The monitor then uses this information to restore the sound so that it can be heard through the speaker in the unit.
In addition to creating an audible representation of the heart rhythm for all that can hear, prenatal doppler units can perform other functions. Some units are able to calculate the heart rate and display it on the screen as rhythms per minute. If the unit does not perform this function, the heart rate is easily calculated by counting rhythms for ten seconds and then multiplying six to obtain heart rate. Some units are also able to record the sound of HeartBeat, which can then be downloaded to your parents' computer to be shared with friends and family.
usesin the office or at home, prenatal doppler is easy to control. First, an ultrasonic gel is applied to the mother's belly to help the sound of sound waves, and then the probe moves slowly around the circular movement until the heart rhythm is located. The probe is then held in place to listen. These devices are considered to be a safe and routine part of prenatal care and many mothers are looking forward to hearing the sounds of the heart of their child at every visit. For mothers who want to listen at home to make sure the health of their child is available for purchase or rent
