There seems to be some confusion regarding the perceived differences between ultrasound machines (sonogram devices) used to obtain an image and fetal heart rate monitors that allow you to listen to your baby’s heartbeat.
Although both technologies use sound waves to obtain information, the waves of the ultrasound machine are much higher (more than 40 times higher) than those of the fetal heart rate monitor. In addition, the frequency and variation of the probe used (2.5 to 10 MHz probes) and the power levels (up to 740 watts) require a trained ultrasound technician to perform the ultrasound, while the fetal heart rate monitor has only a few probes (2, 3, 4, 8 MHz) and a single power level (less than 20 watts), so it can be used easily and safely by anyone.
Furthermore, the fetal Doppler is not the same as the blood flow Doppler (used to check for umbilical cord abnormalities). Ultrasound machines used to obtain images, with the fetal Doppler test of the umbilical cord, are medical procedures that should only be performed by a certified technician. Fetal heart rate monitors have been used for more than 50 years and are approved for home use by pregnant women.
If you have any other questions or concerns regarding renting a fetal Doppler for home use, please call or email us, or talk to your healthcare professional.
