Expectant parents like to use new technology to keep an eye on their growing baby, and the innovations in baby heart monitors have indulged that protective urge to the fullest. But technology is only helpful so long as it’s fully understood, and people who want to make use of baby heart monitors need to know roughly how they work and what they can and can’t do. If you have a baby coming along and you’re interesting in knowing more, keep reading.
Baby heart monitoring devices are ultrasound-based products that amplify the sound of an infant’s heartbeat while simultaneously filtering out other bodily sounds. In this sense, it is distinguished clearly from microphones that simply amplify all sounds without discretion. A baby heart monitor can be used to detect heartbeats as soon as two and a half months in the course of pregnancy. This ultrasound works in a manner similar to that of how bats see, or submarines navigate. A frequency is sent out to bounce from point to point. The device then analyzes the speeds of these bounces, and translates it into the equivalent heartbeat.
It’s a very safe and trustworthy means of discerning and interpreting sounds and objects, without being unpleasant or physically invasive. A heart monitor will result in a sound not dissimilar to the ‘Doppler effect’ of a train whistle. The sound becomes gradually louder, and then quickly drops in volume and tone. A decent heart monitor will track the frequency and general rhythm of the baby’s heartbeat, giving expectant mothers a limited ability to track the growing baby’s wellbeing while it’s still inside them. In fact, baby heart monitors are sufficiently effective and versatile that even medical professionals use them for tracking other things via ultrasound.
However, baby heart monitors aren’t perfect. Casual users who aren’t trained in the use of ultrasound can misunderstand heartbeat sounds. You shouldn’t assume that your baby is healthy just because you hear a heartbeat! A baby heart monitor isn’t meant to replace regular checkups by professional doctors, so use them as a supplement for your baby’s wellbeing, not a substitute for medical experts. In addition, not all baby heart monitors are made equal.
When shopping for a heart monitor, it’s important to do background research on the company and the product model, to make sure you’re getting a good deal for the money you put down. A poor baby heart rate monitor is worse than not buying one in the first place. Remember that you get what you pay for! Heart monitors can be had for as little as fifteen dollars, but if you want a quality device, you should be ready to spend anywhere from thirty to sixty, at a minimum. If you want to be absolutely sure you’re getting a good heart monitor, look for one that specifically has FDA approval.
