Women's oxygen demand doubled when pregnant. According to a study, an estimated 60 to 70 percent of women experience shortness of breath during pregnancy. Long-term hypoxia is harmful to the pregnant woman's body, and is not conducive to the development of the fetus, and may even cause fetal death.

More and more doctors recommend that Oxygen is supplemented with an oxygen generator which is the most direct and useful way.It not only can improve the arterial blood oxygen content of pregnant women, is beneficial to improve the physical condition of pregnant women, and after oxygen, it can rapidly increase the blood oxygen of the mother, placenta and fetus. Partial pressure, blood oxygen content and oxygen reserve make the placenta get sufficient oxygen supply, accelerate the penetration of nutrients into the fetus, improve fetal hypoxia and promote fetal growth and development.
