Precautions for oxygen delivery

If a person is suddenly exposed to a plateau environment, he will not be able to absorb enough oxygen and will need to always have an oxygen tank on hand. Small oxygen tubes can be purchased on the market. Through some simple connecting devices, he can breathe oxygen smoothly and eliminate the feeling of physical fatigue. For example, in Tibet, many tourists carry small oxygen tanks with them. So, what are the precautions for oxygen administration?

1. Purpose and precautions of oxygen inhalation

1. Do not inhale oxygen for a long time. Long-term oxygen inhalation may cause the blood oxygen concentration in pregnant women to be too high, which may cause internal environmental disorders in pregnant women.

2. Avoid excessive blood oxygen concentration in pregnant women. Once it is too high, it will irritate the fetal blood vessels and affect the developing retina of the fetus. In severe cases, it will cause damage and blockage of the retinal endothelium, leading to retinopathy, glaucoma and other problems.

3. Pregnant women should not breathe oxygen blindly. For the health of themselves and the fetus, they must follow the doctor's instructions before breathing oxygen. If a pregnant woman has heart disease or insufficient blood and oxygen supply, poor placental function, the fetus has intrauterine growth retardation, the fetus has a slow heart rate or fetal respiratory distress, oxygen can be administered under the guidance of a doctor. In fact, pregnant women can breathe fresh oxygen by taking a walk under green trees or in the square.

4. 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. In addition, the concentration, amount and time of oxygen inhalation are slightly different for different pregnant women. It is not recommended for pregnant women to inhale oxygen at home by themselves. If they inhale oxygen at home, it is easy to damage their health if they cannot control the oxygen concentration and flow rate. In addition, oxygen therapy is phased. 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.

2. Benefits of oxygen inhalation 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.

Pregnant women often use oxygen as a method to treat fetal hypoxia. Therefore, it would be a very happy thing if you never have to feel what it is like to breathe oxygen throughout your life. After learning about oxygen inhalation, do you feel like a new world has been opened? If the baby is suffering from hypoxia, pregnant women should pay more attention to rest and remember not to overwork.
