How long does it take for pregnant women to breathe oxygen? Precautions for pregnant women to breathe oxygen

In some special cases, pregnant women must breathe oxygen to meet the fetus's demand for oxygen. For expectant mothers with weak constitution, anemia, etc., if it is confirmed that oxygen inhalation can better protect the health of the fetus, it is beneficial and harmless to breathe oxygen at regular intervals and in fixed quantities.

20-30 minutes each time, 1-2 times a day. Pregnant mothers cannot breathe oxygen without a regular pattern, breathe as much as they want, breathe oxygen scientifically, do not breathe for too long at a time, about 20-30 minutes is better, do not exceed 30 minutes, breathe oxygen 1-2 times a day, you can also follow the doctor's advice. Do not breathe oxygen at high concentrations for a long time continuously, there is a risk of causing fetal retinal detachment.

1. Pay attention to the oxygen inhalation time

Pregnant mothers cannot breathe oxygen without a regular pattern. They can breathe as much as they want, and they cannot breathe one day and stop for two days. The correct attitude is to follow certain rules and breathe oxygen scientifically. Do not breathe for too long at a time, 10 to 20 minutes is better, and no more than 30 minutes. After a week of continuous breathing, take a break of one to two weeks in between, or according to the doctor's guidance.

2. Be careful not to inhale high concentrations of oxygen

Pregnant women should pay attention to not inhaling too much oxygen, and the oxygen flow rate must be controlled below 1 liter/minute. This is because if pregnant mothers inhale high-concentration oxygen for a long time, the blood oxygen concentration in the body will be too high, which will stimulate the fetal blood vessels through the placenta. In particular, the developing retinal blood vessels of the fetus are extremely sensitive to high concentrations of oxygen, which may cause damage to the retinal vascular endothelium and blockage, and then cause retinopathy, glaucoma and other problems.

3. Be careful not to inhale oxygen for a long time

Oxygen therapy for pregnant women is a phased process. Once the problems of insufficient blood and oxygen supply and intrauterine growth retardation of the fetus are alleviated, oxygen therapy should be stopped. This is because long-term oxygen inhalation may cause the blood oxygen content in the pregnant woman to be too high, which will cause environmental disturbances in the pregnant woman's body.

Although oxygen inhalation is good, not all pregnant women need it, unless there are special circumstances: 1. For pregnant women with anemia, poor lung function, heart disease, etc., the hospital recommends oxygen inhalation. 2. For expectant mothers with weak constitution, anemia, etc., if it is confirmed that oxygen inhalation can better protect the health of the fetus, it is beneficial to inhale oxygen at regular intervals and in fixed quantities. 3. If the fetus has growth retardation or placental malfunction, fetal heart rate abnormalities, etc. in the uterus, oxygen inhalation can improve the condition.

Oxygen can be inhaled for about a week. Pregnant women cannot inhale oxygen for one day and then stop for two days. They must follow a certain pattern. Generally, after inhaling oxygen for a week, they should take a break of one to two weeks before inhaling again. The time should not be too long to avoid side effects. It can also be determined according to the doctor's instructions. In addition, oxygen therapy is staged. Once the problems of insufficient blood supply and oxygen supply for pregnant women and intrauterine growth retardation of the fetus are alleviated, oxygen therapy should be stopped. Otherwise, it will be detrimental to health.
