Generally, it is not recommended for pregnant women to take oxygen at home, but it should be analyzed on a case-by-case basis. If there are special reasons why they cannot take oxygen in the hospital, or if they are guided by a professional physician, they can also take oxygen at home. First of all, oxygen cylinders are explosive, and if they are not operated properly, they may explode, leading to dangerous situations and threatening the life of the pregnant woman and her fetus. Secondly, although the operation of the oxygen machine seems to be uncomplicated, there are high requirements for the concentration and flow of oxygen when inhaling oxygen, which is difficult for non-professionals to master. If the oxygen intake is too much, it may cause oxygen toxicity, and in serious cases, it may affect the fetus’ vision development, which is not good for the health of mother and child. Therefore, pregnant women should avoid taking oxygen at home by themselves as much as possible. When pregnant women show signs of oxygen deficiency, have discomfort such as chest tightness, shortness of breath, prolonged mental discomfort or abnormal fetal movement, it is recommended to go to the hospital for relevant examinations. If it is found after the examination that oxygen is really necessary, it can be done under the monitoring of medical professionals and fetal heart monitoring is done after oxygen intake until it is qualified and then discharged. Of course, if for some reasons oxygen cannot be administered in the hospital, or if the doctor recommends and instructs oxygen administration at home, or if there is a family member at home who specializes in obstetrics and gynecology and can effectively grasp the indications for oxygen administration and the precautions related to oxygen administration, oxygen can also be administered at home.
