Handheld fetal dopplers are actually quite easy to use and understand. A fetal doppler is used to listen to a baby’s heartbeat while it is still in the womb. By using ultrasound technology, a fetal doppler heartbeat monitor sends high frequency sound waves into your abdomen. When the sound waves encounter movement, such as your baby’s heartbeat, it sends a signal back to the device through the handheld probe. The signal is then translated into a sound which is then amplified so you can hear it.
Fetal dopplers are used by medical professionals every day to detect heartbeats of babies in the womb. They are completely safe and do not require a prescription. The waves emitted by a fetal doppler are about 40 times lower than those emitted from an ultrasound machine. Every HomeDoppler Handset we sell is registered with the FDA to ensure safety and quality.
HomeDoppler can be used as early as week 12. Due to several physiological aspects of the pregnancy however, such as baby size, placenta position and others, it can in some cases, be challenging to locate the baby’s heartbeat and more difficult to maintain stability. As the pregnancy progresses, and towards week 18 the device becomes easier to use.
Typically, fetal doppler measurements are reliable but there are some factors that could cause the measurement to read improperly including: • Smoking tobacco products. • Drinking large amounts of caffeine. • Extra noises, such as the mother's heartbeat or stomach rumbling, can mask the signals. • Sleep patterns. • Baby movement.
It is recommended that you don’t use a fetal doppler device until the 12th week of pregnancy. You might not hear the heartbeat until the 14th-16th week however, this can be different from person to person.
