When choosing a baby heart rate monitor, there are several aspects to consider. One decision is whether to buy or rent a monitor. Other factors include the frequency of the monitor and whether or not it comes with audio playback. In addition, it's usually a good idea to only pick a well-tested product to ensure safety for both the woman and unborn child.
Deciding whether to buy or rent a baby heart rate monitor will be determined by a few criteria. If the mother plans on having more children in the future or is not concerned with expenses, then purchasing the monitor is usually the best choice. On the other hand, if the mother is unsure about having future children or not interested in making a long term investment, then renting is often the best option. Prices can vary, but higher-end models are often quite expensive, so this decision should be made carefully.
Another option to consider when choosing a baby heart rate monitor is whether the mother wants a product with audio playback or not. Many monitors on the market now have the ability to record the baby's heartbeat. This can be especially useful if the baby has any health problems like irregular heartbeats or heart murmurs. It also provides the option of letting a doctor listen to the audio at a later time, which can aid in making a proper diagnosis. Although it can be helpful in some situations, this option isn't mandatory and typically adds to the price of the product.
The frequency of a monitor is another factor to take into consideration when looking at different products. Most high quality heart rate monitors usually come in either 2 or 3 gigahertz frequencies. Monitors with a frequency of 3 gigahertz are usually more sensitive and can detect heartbeats in early pregnancy. If a product has a higher frequency, in the range of 4 to 8 gigahertz, then it is usually not intended for listening to a baby's heart.
Another feature that is very important when choosing a baby heart rate monitor is sufficient testing and approval from a government agency. For consumers in the United States, a product that has been approved by the FDA will have been scrupulously tested to meet safety standards. This should prevent any negative side effects of use for both the mother and developing child. Selecting a product that does not bear the proper agency approval is not advised.
