Knowledge of oxygen inhalation in pregnant women Precautions for pregnant women on oxygen inhalation

Regular oxygen inhalation during pregnancy can increase the arterial blood oxygen content of pregnant women, which is beneficial to improving the physical performance of pregnant women and the growth and development of the fetus. Pregnant women cannot actively inhale oxygen due to physical reasons, and must rely on the outside world to passively inhale oxygen to the body, and hyperbaric oxygen has a good effect on threatened abortion.

Pregnant women inhale oxygen helps to improve blood circulation, increase oxygen carrying capacity, prevent fetal hypoxia, and has a certain prevention and treatment effect on gestational hypertension, and due to the increase of circulating resistance during pregnancy, oxygen inhalation can improve the symptoms of insufficient blood supply and oxygen supply to the organs to meet the oxygen demand of organ metabolism, thereby indirectly improving the quality and safety of pregnancy.

The number of breaths after pregnancy remains unchanged, but the ventilation per minute increases from 8 liters before pregnancy to 11 liters of full-term pregnancy, due to the increase in ventilation, pregnant women need to inhale more oxygen to ensure the need for oxygen for the fetus and placenta, and exhale more carbon dioxide when exhaling, which is conducive to the diffusion and emission of carbon dioxide in the fetus to the mother.

Therefore, the most common and effective way to give the mother oxygen before the baby is born.

The use of atmospheric oxygen**, that is, by giving the mother oxygen for 15 minutes, resting for 5 minutes in the middle, and inhaling for another 15 minutes, it can quickly increase the partial pressure of blood oxygen, blood oxygen content and oxygen reserves of the mother, placenta and fetus, so that the placenta can get sufficient oxygen**, accelerate the penetration of nutrients in the mother's body into the fetus, improve fetal hypoxia, and promote fetal growth and development.

Therefore, in the case of fetal intrauterine distress, fetal intrauterine growth retardation, placental dysfunction, fetal arrhythmia, etc., the use of atmospheric oxygen can achieve satisfactory results, and it is very safe.

In addition, pregnant women with heart failure, infective endocarditis, cyanotic congenital heart disease, and asthma need oxygen to adjuvant it**.

When you feel unwell, tired, or dizzy, you may wish to inhale fresh and pure medicinal oxygen, which can make your mother and child healthier.

Normally, the fetus receives oxygen and nutrients from the outside world through the umbilical cord of the pregnant mother, which is when the pregnant mother is in good health and normal. However, sometimes in the process of pregnancy, sometimes the physical condition does not allow for a lack of oxygen, and the fetus is also faced with insufficient oxygen. There is also a lack of oxygen when labor is approaching, and oxygen inhalation helps to give birth.

Next, let's take a look at the precautions for pregnant women taking oxygen. Precautions for pregnant women receiving oxygen.

1. The normal development of the fetus will enhance the metabolic activity, so it needs sufficient oxygen, and the supply of oxygen to the uterus has an important impact on the fetal IQ. Hypoxia during pregnancy can damage the fetal brain and lead to fetal mental retardation, sluggishness, stupidity and even lifelong disability. According to statistics, 90% of children have low IQ due to pregnancy, intrapartum and neonatal asphyxia, and the number of breaths per minute of pregnancy has increased from 8 liters before pregnancy to 11 liters per minute of full-term pregnancy, and pregnant women need to inhale more oxygen due to the increase in ventilation.

2. Ensure the oxygen needs of the fetus and the placenta, and exhale more carbon dioxide during inhalation, which is conducive to the diffusion and emission of carbon dioxide in the fetus to the mother. Therefore, before the baby is born, it is often used to give the mother oxygen as an effective method. Through regular oxygen inhalation (portable oxygen cylinders), the partial pressure of oxygen in the mother, placenta and fetal blood oxygen, blood oxygen content, and oxygen reserves are rapidly increased so that the placenta can obtain sufficient oxygen** and accelerate the nutrients in the mother's body.

Infiltrate into the body to improve fetal hypoxia, promote fetal growth and development and brain cell development, and treat heart, lung, kidney and other diseases. Pregnant women insist on regular oxygen inhalation, avoid organ failure, prolong the growth time of the fetus, and ensure the maturity of the fetus.

3. When you are pregnant, doing more exercise and going to the park will be more effective than oxygen. If you must go, you can take oxygen after 3-4 months, and it is recommended to take it at most once every half a month. The above is a list of precautions for pregnant women taking oxygen.

According to the above information, we can see that the normal development of the fetus requires oxygen, and oxygen inhalation is still necessary under special circumstances, but oxygen inhalation should also pay attention to some things in case of accidents. It's best to do more outdoor aerobic exercise.

The existence of oxygen maintains the normal survival of all living things on the earth, and all living things are inseparable from oxygen. For pregnant women, they have the responsibility to ensure the healthy development of both lives. If some pregnant women have weak physical fitness, they will have symptoms of chest tightness, and they will choose to take oxygen at this time.

Increase the oxygen content of the mother's blood and relieve the lack of oxygen in the fetus. During pregnancy, due to the rapid increase of maternal metabolism and the increase of the burden on various tissues and organs, the need for oxygen is very much, and when the mother is hypoxic, it will affect the development of the fetus, resulting in intrauterine hypoxia in the fetus. Oxygen inhalation during pregnancy can mainly increase the oxygen content of maternal blood, alleviate fetal hypoxia, ensure the normal development of the fetus, and prevent developmental problems in the fetal nervous system.

If the economic conditions allow, in the third trimester of pregnancy need to be routinely inhaled, the specific situation depends on the mother's physical condition, and the specific requirements of the hospital doctor, the oxygen concentration should not be too high, the oxygen inhalation time should not be too long, each time the oxygen inhalation can be between 30-60 minutes.

In addition to the benefits of oxygen inhalation for pregnant women, it is also good for pregnant women themselves, which can alleviate some uncomfortable symptoms of pregnant women, such as dizziness, fatigue, physical discomfort and other symptoms of pregnant women.

This improves the hypoxia of the fetus in utero. Pregnant women who require oxygen during pregnancy will have two main conditions: one is that fetal movements are frequent, reduced, or absent, but the fetal heart rate is normal on Doppler testingAnother situation is the third trimester of pregnancy, fetal heart rate monitoring does not respond or the response is unsatisfactory, the S D value is elevated, oligohydramnios, and the pregnant woman has obstetric complications, such as gestational hypertension, gestational cholestasis syndrome, gestational diabetes, etc.

1. Pregnant women generally do not feel anything when inhaling oxygen, which is similar to the feeling of normal breathing, and there may be uncomfortable feeling in the nasal tube, but this is a normal phenomenon. Although oxygen inhalation has many benefits for pregnant women, it cannot be inhaled blindly, and oxygen must be inhaled according to the doctor's guidance.

2. Different pregnant women have different oxygen concentration, oxygen inhalation and oxygen inhalation time, and doctors generally do not recommend pregnant women to inhale oxygen at home, because if the concentration of oxygen inhalation is not well controlled, it will have an impact on physical health. It is also necessary to pay attention to the time of oxygen inhalation, if the pregnant woman has insufficient blood supply and oxygen supply after oxygen inhalation, and the problems of fetal intrauterine growth retardation have improved, you can stop oxygen inhalation.

Excessive oxygen inhalation can lead to fetal toxicity and affect the fetus's vision, so you must be careful. If the doctor does not recommend oxygen, pregnant women should not take oxygen without permission. It is recommended that pregnant women go outdoors more often, exercise appropriately, and the park is a natural oxygen bar.
