When a female friend is pregnant, the fetus will get oxygen and nutrition through the placenta and umbilical cord. In case of fetal distress, you should take oxygen in time, which can avoid the danger of your baby. However, pregnant women should take oxygen scientifically, and they should never take oxygen for a long time. So, what are the hazards of long-term oxygen inhalation during pregnancy?
Pregnant women don’t need oxygen at ordinary times, and only need oxygen when there is insufficient oxygen supply and fetal respiratory distress. Moreover, we should pay attention to the fact that if oxygen is inhaled for a long time, it will do great harm. This will not only harm the health of pregnant women, but also bring great harm to the fetus.
If oxygen is inhaled for a long time during pregnancy, the concentration of blood oxygen will be too high, which will make the physical environment disorder, and then stimulate the fetus through the placenta. Especially during the development of fetal retinal blood vessels, if oxygen is inhaled for a long time, it is easy to damage fetal retinal blood vessels, which will lead to some diseases, such as glaucoma and retinopathy.
When pregnant women breathe oxygen, they must be careful, and they must never breathe oxygen at will. If you have heart disease or insufficient oxygen supply during pregnancy, you can only take oxygen under the guidance of a doctor, and the time should not be too long. Usually, you can take oxygen for 15 minutes. If you breathe oxygen continuously for one hour, it will cause harm. If pregnant women often lack oxygen at ordinary times, they can breathe fresh 空 air outdoors at ordinary times.
