Symptoms of hypoxia in eight-month pregnant women

Having a baby in the belly does not mean that the baby is in a normal condition. In fact, it is very likely that the baby in the belly will be affected and suffer from hypoxia due to various uncontrollable factors. Once this phenomenon occurs, it is likely to lead to serious consequences, especially for pregnant women in their eighth month of pregnancy. Therefore, mothers must discover problems as early as possible to avoid bad things from happening.

1. Abnormal fetal heart rate. The normal fetal heart rate is regular and strong, usually about 120 to 160 beats per minute, and can be heard after 12 weeks of pregnancy. If the fetal position is normal, on the left or right side of the pregnant woman's lower abdomen, where the fetal back is located, it can be listened to with the help of simple instruments. Before the fetal movement decreases, the fetal heart rate becomes too frequent. If it exceeds 160 beats/minute, it is a sign of early fetal hypoxia. If the fetal movement decreases or stops, and the fetal heart rate is less than 120 beats/minute, it is a sign of late fetal hypoxia. The position for listening to the fetal heart rate should be at the position specified by the doctor, but it should be noted that if the fetal heart rate is abnormal, it should be listened to again after 20 minutes; if the fetal heart rate is fast, it should be listened to again when there is no fetal movement.

2. Changes in fetal movement. Fetal movement is a normal physiological activity of the fetus, which can be felt by pregnant women at 18 to 20 weeks of pregnancy. The fetal movement varies for different fetuses. Generally, the movements of a quiet fetus are gentler and less frequent, while the movements of an excited fetus are larger and more frequent. If a originally active fetus suddenly becomes quiet, or a originally quiet fetus suddenly becomes restless, and the fetal movement is less than 10 times/12 hours or more than 40 times/12 hours, there is a possibility of fetal intrauterine hypoxia. This is because the fetus is trying to reduce oxygen consumption or because hypoxia affects the central nervous system. Pregnant women can calculate fetal movements while sitting or lying down. They should count for one hour at a fixed time in the morning, noon and evening. The total number of fetal movements in 12 hours should be added up and multiplied by 4.

3. Growth stagnation. Fetal growth will also be slowed after hypoxia. The growth of the fetus can be known by measuring the height of the uterine fundus, which is the distance from the top of the pubic symphysis to the highest point of the uterine fundus. Under normal circumstances, the diameter of the breasts should increase by about 1 cm per week after the 28th week of pregnancy. Pregnant women can measure their blood pressure regularly at home or in the hospital. If there is no growth for two weeks, further investigation should be conducted.

Once hypoxia occurs, it is best to go to the obstetrics department to breathe oxygen in time. It is very important to breathe low-density oxygen every one or two days, or every two or three days (you can decide for yourself based on the baby's condition or listen to the doctor's advice). Oxygen inhalation is good for both pregnant women and babies. You should also pay attention to your daily living habits. When sleeping, pregnant women must be careful not to press the baby, and it is best to sleep on the left side. Also be careful not to squeeze your abdomen during daily activities, such as bending over to pick up something.
