Symptoms of hypoxia in babies at 30 weeks of pregnancy

From the moment of pregnancy, the expectant mother is terrified about the baby in her belly and becomes worried at the slightest movement. Natural fetuses are more sensitive, so it’s okay to care a little, but worrying too much will cause depression in pregnant women. Especially in the late stages of pregnancy, many expectant mothers worry about fetal hypoxia. So what are the symptoms of insufficient oxygen for a baby at 30 weeks of pregnancy?

The main symptoms of insufficient oxygen in babies at 30 weeks of pregnancy are:

1. Changes in baby's fetal movements

Fetal movement is a normal physiological activity of the fetus. Generally, pregnant women can feel the movement of the fetus at 18-20 weeks of pregnancy.

The fetal movements of different fetuses are also different. Generally speaking, the fetal movements of quiet fetuses are smaller and the frequency of fetal movements is also less. The fetal movements of excited fetuses are large and frequent.

The fetus's oxygen consumption is reduced or insufficient oxygen affects the nerve center, which can cause abnormal activities. If an originally cheerful fetus suddenly becomes quiet, or an originally quiet fetus suddenly becomes restless, and the frequency of fetal movement is less than 10 times/12 hours or more than 40 times/12 hours, it means that the fetus may have insufficient oxygen in the uterine cavity.

Pregnant women should closely observe the fetal movements. If any abnormalities are found in the fetal movements, it is possible that the fetus is suffering from fetal hypoxia and requires immediate medical treatment.

2. Abnormal fetal heartbeat

Normally, the fetal heart rate of a baby is regular, about 120-160 beats per minute. Pregnant women can rely on fetal heart rate monitors to observe the fetal heart rate.

If the fetal heartbeat is abnormal, it should be listened to again after 20 minutes. If the fetal heartbeat is too fast, it should be listened to again when there is no fetal movement. If the fetal heartbeat exceeds 160 beats/minute, it is a signal of early fetal oxygen deficiency; if the fetal heartbeat is lower than 120 beats/minute or even stops, it is the end of fetal hypoxia.

3. Fetal development stagnates

The development of the fetus can be known by measuring the uterine height. Normally, after 28 weeks of pregnancy, the uterine height should increase by about 1 cm per week. If the fetus is deprived of oxygen, the growth and development of the fetus will also be slow. Pregnant women can regularly measure the height of the uterus at home or in the hospital. If there is no increase for half a month, further examination is required.

What should pregnant women do if they lack oxygen?

During pregnancy, pregnant women have to supply the growth of the fetus, so the burden on system structures such as the respiratory system, respiratory tract, and urogenital system is increased. The blood flow will gradually increase, the heart rate will become faster, and the lung ventilation volume will increase.

Many people will feel that they are short of oxygen and often need to take a deep breath to feel comfortable. This is normal. If you are originally healthy and have no heart or lung disease, this phenomenon does not require special treatment. However, if the feeling of chest tightness, shortness of breath or breathlessness is very severe, daily activities are restricted, and you cannot lie flat, then you should see a doctor for electrocardiogram, heart function, ultrasound echocardiography and other tests.

1. First of all, you need to have a clear understanding from a psychological point of view. The reactions to pregnancy vary greatly from person to person. You need to maintain a happy mood and don't need to be nervous or anxious.

If all indicators are normal and the fetus's development is in line with normal rules, you can use medication, such as oxygen supply, regular fetal monitoring, and biophysical tests, and don't be too nervous.

2. Ensure the supply of nutrition and diet, and use culture fluid intravenously when necessary to enhance immunity.

3. Oxygen health care during pregnancy: 3 times a day, each time oxygen supply (low oxygen) for 3 to 5 minutes. Pregnant women should receive appropriate oxygen supply to a certain extent to prevent various symptoms of hypoxia and promote the healthy growth and development of the fetus.

4. Sleeping position on the left side: It is best for pregnant women to sleep on their left side, which is beneficial to the oxygen production of the fetus.

5. Pay attention to your environment, pay attention to the ventilation in the room, and eat properly.
