What should pregnant women pay attention to when receiving oxygen?

The nutrients absorbed by the fetus are supplied through the mother's umbilical cord. Pregnant women should pay attention to balanced nutrition, avoid staying up late, and maintain adequate sleep. If there are no problems in all aspects of the prenatal check-up, pregnant women do not need to use oxygen. Reasonable oxygen inhalation by pregnant women can prevent fetal hypoxia, but oxygen inhalation depends on the condition of the pregnant woman. It should be determined according to her own situation. Let's see what pregnant women should pay attention to when receiving oxygen.

1. Reasonable oxygen inhalation for pregnant women

Reasonable oxygen inhalation for pregnant women can increase the oxygen supply to the fetus and ensure normal breathing of the fetus. However, oxygen inhalation should be carried out according to the physical condition of the pregnant woman, especially after examination in the hospital, it should be decided whether it is necessary to inhale oxygen. If a pregnant woman has frequent uterine contractions or fetal movements, or a rapid fetal heart rate, these are manifestations of fetal intrauterine hypoxia and these pregnant women need oxygen to better protect the health of the fetus. In addition, for some pregnant women with weak constitutions, such as anemia, heart disease, or poor lung function, doctors generally recommend oxygen.

The time for oxygen inhalation is strictly controlled, not exceeding half an hour each time, and can last for a maximum of one week. If it exceeds a week, there may be side effects. Excessive oxygen inhalation can lead to oxygen poisoning, which will have adverse effects on the fetus and pregnant women, and even affect the fetus's vision. Hospitals will control the amount of oxygen inhalation more reasonably. Therefore, it is best not to inhale oxygen at home by yourself, but to go to the hospital.

Pregnant women should often go to places with good air to breathe fresh air and do appropriate aerobic exercise. This way, the oxygen absorbed is the most natural and healthiest, which is beneficial to the health of pregnant women and fetuses.

2. Is oxygen inhalation good for the fetus?

After pregnancy, a woman's breathing rate remains unchanged, but her minute ventilation volume increases significantly compared to before pregnancy. In this way, the amount of oxygen that pregnant women need to inhale into their bodies will increase greatly to ensure the oxygen supply needs of the fetus and placenta. Therefore, it is very beneficial for pregnant women to breathe oxygen.

The most common and effective treatment for prenatal care is oxygen therapy for pregnant women. Normothermic oxygen therapy, which is a treatment method in which the mother inhales oxygen for 15 minutes, rests for 5 minutes, and then inhales for another 15 minutes, can rapidly increase the blood oxygen partial pressure, blood oxygen content and oxygen reserve capacity of the mother, placenta and fetus, so that the placenta can get sufficient oxygen supply, accelerate the penetration of nutrients in the mother's body into the fetus, improve fetal hypoxia, and promote fetal growth and development.

Therefore, in cases of fetal distress, intrauterine growth retardation, placental dysfunction, fetal arrhythmia, etc., the use of normobaric oxygen therapy can achieve satisfactory therapeutic effects and is very safe.

In addition, pregnant women with heart failure, infective endocarditis, cyanotic congenital heart disease, and asthma need oxygen for auxiliary treatment. When a pregnant woman feels unwell, tired or dizzy, she may as well breathe some fresh and pure medical oxygen. This can keep the fetus and the pregnant woman healthier.

IV. Precautions for pregnant women to take oxygen

1. First of all, long-term unnecessary oxygen inhalation may cause excessively high blood oxygen concentration in pregnant women, causing internal environmental disorders.

2. Secondly, if the blood oxygen concentration in pregnant women is too high, it will stimulate the fetal blood vessels through the placenta. In particular, the developing retinal blood vessels of the fetus are extremely sensitive to high concentrations of oxygen, which may cause damage to and blockage of the retinal vascular endothelium, and further lead to retinopathy, glaucoma and other problems.

3. From this we can see that for the health of yourself and the fetus, you must listen to your doctor's advice on whether you need oxygen during pregnancy. If the examination reveals that the pregnant woman has heart disease, insufficient blood and oxygen supply, poor placental function, or the fetus has intrauterine growth retardation, slow heart rate, respiratory distress, etc., oxygen therapy can be given under the guidance of a doctor. If it is just to allow yourself and the fetus to breathe more fresh air, pregnant women might as well take half an hour every day to take a walk in a tree-lined park or square and take deep breaths.

4. Even if you really need oxygen during pregnancy, it is best to go to the hospital for oxygen therapy under the guidance of a doctor, because the flow, concentration, time, etc. of oxygen therapy are slightly different depending on the patient's condition. If you breathe oxygen at home and fail to control the oxygen concentration and flow, it can easily damage your health. In addition, oxygen therapy is a phased approach. Once the problems of insufficient blood and oxygen supply to the pregnant woman and intrauterine growth retardation of the fetus are alleviated, oxygen therapy should be stopped. Otherwise, it will be detrimental to health.

5. What is the safe flow rate and time for pregnant women to inhale oxygen?

It is best to control the oxygen flow rate at a low point, which is good for the child. If pregnant women inhale oxygen concentrations that are too high for too long, it can cause retinal detachment in the fetus. Proper oxygen inhalation is beneficial to both the fetus and the pregnant woman, and the flow rate should be controlled below 2 liters/minute.
