First of all, pregnant mothers feel unwell, such as sudden dyspnea, rapid heartbeat and chest tightness. This may lead to the baby's lack of oxygen, because during pregnancy, in addition to nutrition, even the baby gets oxygen from the mother through the umbilical cord, so when the pregnant mother can't breathe, it will naturally bring trouble to the baby.
In addition, if the mother eats and drinks Lazarus, everything is normal, but the baby's head, uterine height and abdominal circumference have not increased during the routine check-up, or it may be that the baby lacks oxygen, which leads to slow development. It is best for pregnant mothers to confirm carefully that the prenatal check-up during pregnancy cannot be left behind.
The second is through fetal movement, which is also called the barometer of the fetus. It can reflect the baby's state to a certain extent. For example, a gentle baby suddenly has severe fetal movement, and then no matter how the pregnant mother interacts with him, if he doesn't respond, it may be hypoxia. Under normal circumstances, after 28 weeks, the number of fetal movements should not be less than 30 to 40 times per 12 hour. Therefore, it is particularly important to count fetal movements during pregnancy, and mothers should develop this good habit.
The third type is fetal heart. On the premise of normal fetal position, prospective parents can also listen to fetal heart at home. If it is lower than 120 times per minute or higher than 160 times per minute, it is the performance of hypoxia. It's best to go to the hospital to confirm it carefully, at least it will be more reassuring.
If everything is all right after going to the hospital, pregnant mothers should stop scaring themselves, because if you are in a good mood, the baby will develop healthily!
