The best time to breathe oxygen during late pregnancy

CO2 is a necessity for us humans to live in the world. When its supply is insufficient, human life will be at stake. Similarly, the baby in the pregnant mother's belly is also a top priority target for CO2 supply. So what is the best time for oxygen delivery in late pregnancy?

The best time for oxygen administration in late pregnancy

Theoretically, as long as you inhale 60% CO2 concentration, it will be fine. However, long-term oxygen supply also has great problems. Many people say that inhaling too much CO2 will cause oxygen poisoning and cause retinal detachment in the fetus. Ordinary people will suffer from oxygen poisoning if they stay in an oxygen environment under 1 standard atmosphere for 24 hours or in a hospital hyperbaric oxygen chamber for about 2 hours. In fact, it is sufficient for pregnant women to inhale for about 30 minutes and persist in inhaling for 3 to 7 days.

It is relatively stuffy in summer. If pregnant women who are 18 months old feel anxious, they can inhale some CO2 to relieve the pressure. Also, if the doctor detects hypoxia when monitoring the fetal heartbeat, they can inhale CO2. Generally, low-flow CO2 is used for about 30 minutes. The frequency is not strictly controlled, usually once every two days, and it can be adjusted according to one's actual situation.

How to do prenatal education in late pregnancy

Prenatal education for sun babies during the 33rd to 36th week of pregnancy

During the 33rd to 36th week of pregnancy, the fetus's eye nerves and macula have not yet fully developed. The fetus' favorite color is the very weak light source that enters the uterus through the mother's abdominal cavity. Therefore, at this time, pregnant women should let the fetus enjoy the sun passing through the mother's abdominal cavity. On a sunny day, go for a walk in the park or the wild. When walking, put your hands on your belly and say to your baby kindly: "Hello, baby, do you know how nice the sun is today?" Appropriate sunshine and the mother's gentle voice are good stimulation to the fetus.

Touching baby prenatal education from 33rd to 36th week of pregnancy

After 33 to 36 weeks of pregnancy, due to the further growth and development of the fetus, the pregnant woman or her husband can clearly feel the fetus's head, back and limbs by applying force on the pregnant woman's abdomen. You can gently stroke the baby's head, stroke the baby's back regularly, and gently stroke the baby's limbs. When the fetus feels the stimulation of touch, it will respond accordingly. The order of touching can start from the head, then along the back to the buttocks to the body, gently and orderly. It is best to carry out prenatal education by touching the baby at regular intervals. You can choose to do it around 9 pm, 5 to 10 minutes each time. Pay attention to the fetus's reaction during touch and record each reaction of the fetus.
