How long is it appropriate to inhale oxygen?

The reason we need to breathe is because there is oxygen in the air, and oxygen is an important factor in maintaining normal physiological functions of the human body. If a person has symptoms of hypoxia, it can easily lead to failure of various body functions, which may threaten his life. When a person reaches a plateau or some of his organs fail, he needs to rely on oxygen to maintain life. But how long is the appropriate duration of oxygen inhalation?

Oxygen is a necessity for us humans to live in the world. When its supply is insufficient, human life is in danger. Similarly, the baby in the pregnant mother's belly is also the key supply target of oxygen. So how much oxygen should pregnant women breathe for?

How long is the appropriate amount of oxygen for pregnant women?

Theoretically, it is sufficient to inhale oxygen with a concentration of 60%, because long-term oxygen inhalation can cause serious problems. Some people have heard that inhaling too much oxygen can cause oxygen poisoning and lead to retinal detachment in the fetus. A normal person will suffer from oxygen poisoning if he stays in a pure oxygen environment under 1 standard atmospheric pressure for 24 hours or in a hospital's hyperbaric oxygen chamber for about 2 hours. In fact, it is enough for a pregnant woman to inhale for about 30 minutes and persist in doing so for 3 to 7 days.

Summer is quite stuffy. Pregnant women who are in their late stages usually feel anxious. They can breathe some oxygen to relieve the pain. Also, when the doctor is monitoring the fetal heart rate, if there is hypoxia, they can breathe. Generally, low-flow oxygen is used for about 30 minutes. There is no strict requirement for the number of times. Generally, it is once every two days. It can also be adjusted according to your actual situation.

What are the benefits of oxygen 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.

At this time, pregnant women need to be given oxygen. By breathing oxygen, pregnant women can quickly increase the partial pressure of blood oxygen in the mother, placenta and fetus, and can increase blood oxygen content and oxygen storage. This can provide the placenta with sufficient oxygen supply, improve fetal hypoxia, and allow the fetus to grow and develop healthily. If the fetus shows signs of growth retardation, placental malfunction, or fetal heart rate disorders in the uterus, effective treatment can be provided through oxygen inhalation to ensure the safety of the fetus.

Therefore, oxygen inhalation for pregnant women can not only relieve their discomfort, such as dizziness, fatigue, physical discomfort and other symptoms, but it is also beneficial to the growth and development of the fetus. However, it is important to pay attention to the correct way of oxygen inhalation. Generally, pregnant women use intermittent oxygen inhalation at normal pressure and low flow.
