Are fetal dopplers safe for the baby?įetal heartbeat dopplers have been approved for use at home by the FDA since they use low emission ultrasound technology. To hear the heartbeat, fetal heart rate monitors’ come with earphones that you connect to hear the sound. Scientifically, once the ultrasound waves are reflected back to the device, the concept of Doppler Effect is used to calculate the shift in frequency and wavelength thereby converting the signal into heart beat. This sound is then amplified by the device and you begin to hear the heartbeat. In the womb, the waves encounter your baby’s heartbeat afterwhich they are reflected back to the Doppler where the heartbeat is converted into sound. They send short pulses of high frequency ultrasound waves which pass through into your baby in the womb. These portable Dopplers work based on the Doppler Effect which was developed by Christian Doppler in 1842.
