Have you seen a fetal doppler?
Fetal doppler is a device used to detect and measure fetal heart rate of the baby inside the mother’s womb. It is only one of the types a fetal heart monitoring has, there are quite a few more. Other types are fetoscope, electronic fetal monitoring, internal fetal monitoring, and telemetry monitoring.
So how does fetal doppler works? It is said, according to fetaldopplerfacts.org, to measure fetal heart rate by emitting and receiving continuous ultrasonic sound waves and emitting the change or shift in pitch frequency of these sound waves. This is called the Doppler Effects.
I want to share what fetal doppler is because I was inspired to post one. I accompany a close friend last week to her OB-GYNE for her monthly pregnancy checkup. And I got curious how fetal doppler works.
