When using the fetal doppler device, there may be a problemin distinguishing the heartbeat of a baby and an adult. But there is a verysimple way in which you can eliminate this problem and it is by counting the heart beatsof a baby with the use of a doppler. The heartbeats of a mother and a baby aredifferent. While mother’s heartbeats are in the range from 60 to 100 BPM,baby's heart beat goes from 120 to 180 BPM. Remember that there are alwaysvariations of heart beat among adults and babies as well. There are fetal dopplers like the sonotrax fetal doppler, which do not have adisplay but the counting of the heart beats can be done just by listening tothe heart beats. This counting needs to be done for 15 or 10 seconds and thenumber you have counted is then multiplied by 4 or 6. If you do this, you willget a number of beat per minute, or BPM. For example, if you have counted heartbeats for 15 seconds, you should multiply the number with 4, or 6 if youhave counted for 10 seconds. In both cases, you will get a result of 60 seconds.If you use sonotrax basic model or any other model with a display, youcan see BPM on a display. The BPM of a baby can be affected by the movement of the baby so do not beconfused by the different baby's BPM. Normal range is considered to be from 120to 180 BPM, but there are factors that influence this number, like pregnancy.The BPM of a baby will become more static as the baby progresses.
Do We Need a Fetal Doppler?
With the use of fetal doppler you can monitor the heart rate and condition ofthe fetus. The fetal heart beat or FHR can also be monitored. You can do thisafter eight weeks of pregnancy if you use a fetal Doppler with a probe of 3MHz.By using these devices, you can even prevent problems like miscarriage due tothe fetus heart beat monitoring. Only 1% of women who use these devices sufferfrom a miscarriage, but in the past, this number was 15%. You can monitor the developmentof your baby and see if and when the problem arises.
You need to be calm since the stress can affect the BPM and even increase therisks associated with low-birth infants. It can even badly influence the child’sgrown up life and lead to withdrawal behavior.
There are some tales that boy's hearts are bigger and thus cause faster heartbeats but this is not true. There is no way the fetal doppler can tell youthe gender of the baby, so you will have to wait for the birth, which will surelygive you the answer.
