Why do you need oxygen during pregnancy? Does hypoxia have any effect on the fetus?

In the middle and late stages of pregnancy, because the baby in the belly begins to develop slowly, and the expansion of the uterus will not only compress the chest, but also the atrium, causing pregnant women to experience symptoms of shortness of breath, chest tightness and shortness of breath. This will mostly cause hypoxia. Excessive hypoxia, if not inhaled in time, is likely to cause problems with the baby's physical development, and may also cause premature birth. If necessary, go to the hospital for examination in time.

1: Why does lack of oxygen occur?

1: Because pregnant women need to provide for the development of the fetus, the burden on various systems such as the circulatory system, respiratory system, and urinary system will increase, the blood volume will gradually increase, the heart rate will increase, the lung capacity will increase, and the oxygen demand will be about twice that of ordinary people.

2: In addition, if the umbilical cord is wrapped around the neck for two weeks or more, it may sometimes cause fetal hypoxia.

3: Pregnant women who are depressed and angry for a long time may suffer from hypoxia

4: Pregnant women may suffer from hypoxia during the cold period

2. Symptoms of hypoxia

1: The pregnant woman herself feels chest tightness, shortness of breath, and difficulty breathing

2: Abnormal fetal movement, for example, the fetus that used to have regular fetal movement suddenly moves violently, or may not move for several days. Pregnant women should go to the hospital for examination in time.

3: The fetus is growth-retarded and is more than two weeks smaller than the current gestational age. It is necessary to check whether it is due to hypoxia.

4: The umbilical cord is around the neck for two weeks and the fetus is slow to develop

5: The fetal heart rate is abnormal. The normal fetal heart rate is 120-160

6. Pregnant women are always in low spirits, yawn and sleep
