Why do pregnant women need oxygen?

After a woman becomes pregnant, her demand for oxygen is very high. Oxygen inhalation is actually to meet the supply of the fetus and placenta. Especially in the late pregnancy, many pregnant women experience difficulty breathing. At this time, oxygen inhalation must be timely, otherwise it is easy to cause hypoxia in the baby. However, not all pregnant women need oxygen inhalation. So in what cases do pregnant women need oxygen inhalation?

Reasonable oxygen inhalation by 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.

Oxygen inhalation has certain benefits for pregnant women, but you cannot do it blindly. You must follow the doctor's instructions for oxygen inhalation treatment. 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.

What are the benefits of oxygen for pregnant women

The number of breaths remains unchanged after pregnancy, but the minute ventilation increases from 8 L/min before pregnancy to 11 L/min in full-term pregnancy. Due to the increase in ventilation, pregnant women need to inhale more oxygen to ensure the oxygen needs of the fetus and placenta, and exhale more carbon dioxide, which is beneficial to the diffusion and discharge of carbon dioxide in the fetus to the mother.

At this time, pregnant women need to be given oxygen. By breathing oxygen, pregnant women can quickly increase the partial pressure of blood oxygen in the mother, placenta and fetus, and can increase blood oxygen content and oxygen storage. This can provide the placenta with sufficient oxygen supply, improve fetal hypoxia, and allow the fetus to grow and develop healthily. If the fetus shows signs of growth retardation, placental malfunction, or fetal heart rate disorders in the uterus, effective treatment can be provided through oxygen inhalation to ensure the safety of the fetus.

Therefore, oxygen inhalation for pregnant women can not only relieve their discomfort, such as dizziness, fatigue, physical discomfort and other symptoms, but it is also beneficial to the growth and development of the fetus. However, it is important to pay attention to the correct way of oxygen inhalation. Generally, pregnant women use intermittent oxygen inhalation at normal pressure and low flow.
