What is the best time to take oxygen during pregnancy?

During pregnancy, pregnant women transmit nutrients to their babies through the umbilical cord and generally do not need oxygen. However, if the fetus kicks the belly frequently or exercises vigorously, it may be a sign of hypoxia in the baby. In this case, pregnant women should breathe oxygen appropriately to allow the baby to grow normally and healthily. So when should they breathe oxygen? How to breathe oxygen? How long to suck? These are all things that need attention. If too much oxygen is inhaled, it may cause abnormal growth of the baby and lead to serious consequences. So what is the best time to inhale oxygen during pregnancy? Below is a detailed introduction.

The most common and effective treatment before the birth of a child is for the pregnant woman to receive oxygen. 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.

Oxygen inhalation can help the fetus develop normally and prevent it from suffocating or even getting in danger due to lack of oxygen. However, excessive oxygen inhalation should not be taken as it will affect the development of the fetal retina and cause abnormal development of the fetal eyes. Suggestions: It is best to breathe oxygen for 20 or 30 minutes every day, often go to places with good air to breathe fresh air, and do more appropriate exercise. When the fetal heart rate is normal during the pregnancy check, you do not need to breathe oxygen. If there is anything else you don't understand, please consult your obstetrician during your pregnancy checkup.

Situations requiring oxygen during pregnancy

Situation 1: Large changes in fetal movement

Changes in fetal movement are one of the most important indicators of whether the fetal vital signs are normal. Generally speaking, pregnant mothers can feel fetal movement between 18 and 20 weeks. Generally speaking, the size of the fetus in each pregnant mother's womb is different, so the amplitude and frequency of fetal movement are different, which is normal.

However, if a fetus that originally had frequent fetal movements suddenly has fewer movements, or a fetus that originally had few fetal movements suddenly has more movements, then this may indicate that the fetus is suffering from intrauterine hypoxia. At this time, you should go to the hospital for examination in time.

Case 2: Abnormal fetal heart rate

The fetal heart rate is regular and strong, and the fetal movement usually lasts 120-160 minutes. If the fetal heart rate is too frequent and exceeds 160 minutes before the fetal movement decreases, it indicates early fetal hypoxia. However, if the fetal heart rate is detected to be less than 120 beats per minute before the fetal movement decreases, it indicates that the fetus is in late stage of hypoxia.

When the above situations occur, if the doctor believes that oxygen inhalation can protect the health of the fetus, he will recommend oxygen inhalation to the pregnant mother. In addition, doctors will also recommend oxygen inhalation for pregnant mothers with poor physical constitution, so everything should be based on the doctor's advice.
