How long is it easy for the fetus to lack oxygen? When a family becomes a prospective parent, they will pay special attention to the children in their bellies, because every child is the darling of their parents and will always pay attention to the physical condition of pregnant women. How long is the pregnancy shared below? Is the fetus prone to hypoxia?
How long have you been pregnant? Fetuses are prone to hypoxia. 1 first, why is the fetus prone to hypoxia in July and August?
The fetus is getting bigger and bigger, but the umbilical cord will not grow. When the baby is idle in Ma Bao's belly, he will often play with the umbilical cord, and some babies may bypass the neck when playing. With the gradual growth of fetal body shape, the unchanged umbilical cord will gradually tighten, which is easy to cause fetal breathing difficulties. If the umbilical cord wraps around the neck of the fetus more, it will have a great impact on the life safety of the fetus.
Amniotic fluid is very important for fetal breathing. Amniotic fluid is enough when the fetus is pregnant. With the growth of fetal problems, more and more amniotic fluid is needed, and some pregnant women have less amniotic fluid in their stomachs. At this time, there is less amniotic fluid. You should know that the fetus breathes in the mother's abdomen by swallowing amniotic fluid constantly. If the amniotic fluid provided by pregnant women is not enough for the fetus, then the probability of the baby's lack of oxygen will be high.
Amniotic fluid has such a great influence on the fetus, so how should we increase the amount of amniotic fluid in the abdomen? Then you should always drink coconut milk, which provides very good amniotic fluid quality. Amniotic fluid is very important for fetal breathing. Only by ensuring the adequate quality of amniotic fluid will it not affect the physical and mental health of the fetus.
Some babies lack oxygen not necessarily because of the uterus, mainly because the number of red blood cells in pregnant women is too small. The weak oxygen delivery ability ensures that one person's breathing is not too big, but delivering oxygen to two people is beyond his ability. At this time, pregnant women should eat more meat to supplement enough red blood cells. Only when there are enough red blood cells in Ma Bao's blood to ensure the oxygen transport ability, can the fetus breathe oxygen normally.
Therefore, pregnant women should arrange oxygen inhalation according to the doctor's reminder. The doctor only judges that the fetus has signs of hypoxia, and will not take this opportunity to lie to you, but to ensure the safety of the fetus. So how to judge that the fetus has been deprived of oxygen?
Second, signs of fetal hypoxia
If pregnant women find that Taitung phenomenon has increased a lot than usual, then the fetus has already experienced hypoxia, because when the fetus can't breathe,
In the case of sufficient oxygen, there will be constant struggle, so fetal movement will be frequent and intense.
At this time, it will be found that after a period of strong fetal movement, it will gradually fade away. This is because the fetus can't breathe oxygen after struggling, so the fetus will struggle to ensure enough physical strength. So the intensity of fetal movement is not so intense, but it will be very weak. When this irregular fetal movement appears, it means that the baby has been deprived of oxygen. At this time, we should immediately rush to the hospital for examination. If there is hypoxia, the doctor will advise Ma Bao to go to the hospital to take oxygen.
Even oxygen inhalation needs professional medical staff, because pregnant women have certain requirements on the time and action of oxygen inhalation. Too long or too short oxygen inhalation time is not suitable for the healthy growth of the baby. Standardized oxygen inhalation can ensure that the baby absorbs enough oxygen and relieve its own hypoxia. Therefore, when pregnant women find signs of fetal hypoxia, they must rush to the hospital in time and actively cooperate with doctors to implement artificial oxygen inhalation.
Conclusion: Doctors who can guide pregnant women to breathe in the front line are all professionals, and their work is related to the lives of many pregnant women, so they are also very cautious about their work, so pregnant women don't have to worry about whether they will take too much oxygen or have other situations. The physical and mental health of the fetus is easily affected by long-term hypoxia. Therefore, we must pay attention to the problem of adequate oxygen for seven or eight months of pregnancy.
How long is it easy for the fetus to lack oxygen? Generally speaking, after 6 or 7 months of pregnancy, the fetus is prone to hypoxia. Because the fetus grows up in the uterus, the space in the uterus may not meet the movements of the fetus, so it is easy to cause intrauterine distress and hypoxia symptoms. Moreover, in the third trimester of pregnancy, after the placenta matures and ages, oxygen supply will be insufficient.
Pregnant women should seek medical attention and replenish oxygen in time when they find the problem of fetal hypoxia. Pregnant women can ensure that the fetus has a supplementary oxygen source by inhaling oxygen, which can improve the blood oxygen concentration of pregnant women and deliver oxygen to the fetus through placental blood flow. Pregnant women usually try to lie on their left side, which can also prevent and improve fetal hypoxia.
When the fetus is hypoxic, it usually shows abnormal fetal movement. Fetal movement is the normal physiological activity of the fetus in the uterus. Generally, pregnant women can feel fetal movement around 18-20 weeks of pregnancy. When the fetal movement is irregular or different from usual, pregnant women should pay attention.
How long does it take to get pregnant? How long does a pregnant woman lie flat?
First, in fact, pregnant mothers can lie flat at the beginning of pregnancy, and there is no need to lie on their left side. Before pregnancy 12 weeks, the uterine body will not exceed the pelvic cavity, and it will not compress the great blood vessels at the back of the abdominal wall, nor will it compress the inferior vena cava, which will affect the blood volume of the heart and cause discomfort to pregnant women and fetal hypoxia. Second, pregnant mothers should sleep as comfortably as possible. Many times, when you fall asleep, you turn over unconsciously. You can put a cushion on each side of your body so that your legs will be more comfortable when you lie on your side.
If the posture is uncomfortable, the baby will react. If you feel it, you will naturally adjust to his comfortable posture, so pregnant mothers don't have to worry too much. So, how should pregnant women lie down? First, the sleeping position of pregnant women is mainly in the left lateral position, which is conducive to oxygen supply to the fetus. It doesn't mean that pregnant women can't use the lying position or the right side lying position, but they can adjust it appropriately to increase their physical comfort. Proper lying position or right lateral lying position will not lead to intrauterine hypoxia and cerebral palsy.
Second, the left lateral position should be 8 ~ 10 months. Because the position of the inferior vena cava is just to the right of the abdominal spine, if you lie to the right, the enlarged uterus will not only compress the inferior vena cava, but also rotate to the right to varying degrees, and the blood vessels will be pulled, thus affecting the normal blood supply of the fetus. Left lateral decubitus can correct and increase the right rotation of uterus, reduce the oppression of uterus on inferior vena cava, improve blood circulation, increase the blood supply of fetus, which is beneficial to the growth and development of fetus.
Manifestations of fetal hypoxia
First, the change of fetal movement: If an active fetus suddenly becomes quiet, or a quiet fetus suddenly becomes restless, fetal movement is less than 18 times/12 hours or more than 40 times/12 hours, there may be intrauterine hypoxia. This is because the fetus affects the central nervous system in order to reduce oxygen consumption or hypoxia. Therefore, pregnant mothers must learn to count fetal movements, so as to better monitor the state of the fetus. After pregnancy, fetal movements 18-20 should be calculated on time.
Pregnant women can sit or lie down when counting fetal movements. Every morning, at noon and at night, they calculate 1 hour at a fixed time, and the number of fetal movements multiplied by 4 times is 12 hour. 2. Abnormal fetal heart rate: The normal fetal heart rate is strong, with 120- 160 times per minute. If the fetal position is normal, the husband can listen on the left or right side of the pregnant woman's lower abdomen, that is, the side where the fetal back is located.
Before the fetal movement decreases, the fetal heart rate is overclocked. If it exceeds 160 beats/min, it is a signal of early fetal hypoxia. The fetal movement is reduced or stopped, and the fetal heart rate is lower than 120 beats/min, which is the late stage of fetal hypoxia. The location of the fetal heart should be in the place designated by the doctor, but it should be noted that if the fetal heart is abnormal, listen again every 20 minutes; If the fetal heart rate is fast, listen to it when there is no fetal movement. The third is growth stagnation: the growth of the fetus will be slow after hypoxia.
By measuring the height of the uterine bottom (the distance from the top of pubic symphysis to the highest point of the uterine bottom), we can know the growth of the fetus. Under normal circumstances, after 28 weeks of pregnancy, it should be increased by about 1 cm per week. Pregnant women can take regular measurements at home or in the hospital. If there is no increase in two weeks, further inspection is needed.
