Intrauterine distress (hypoxia) is a common fetal abnormality in the third trimester, and if not intervened in time, it will lead to permanent damage to fetal organs and eventually even life-threatening.
Many pregnant mothers understand this, but also realize the seriousness of the problem, and want to prevent or prevent fetal hypoxia by inhaling oxygen.
As a result, the Internet is filled with all kinds of oxygen pillows, oxygen cylinders, oxygen concentrators and so on. Pregnant mothers are also flocking to prepare oxygen inhalers like essential medicines. Inhaling oxygen at home without doing anything is always considered beneficial and harmless.
So, is it necessary for pregnant mothers to take oxygen at home? When do I need oxygen? Are there any side effects? How to control the concentration, flow rate, duration, etc. of oxygen inhalation? Below, Dr. Huang explained to the pregnant mothers.
What conditions do I need to take oxygen?
Good steel is to be used on the blade...
When the fetus is dehydrated and needs to be inhaled,
At this time, pregnant mothers inhale oxygen, which is conducive to regulating the blood flow rate of the umbilical artery and regulating the blood circulation of the fetus.
If the fetus is normal, the pregnant mother takes oxygen,
There is no significant effect on the heart function of the fetus.
Therefore, when home fetal heart control is not passed;
When fetal movement is frequent or the fetal movement is significantly reduced, it is inconsistent with the usual fetal movement law;
Or when the pregnant mother herself has uncomfortable symptoms such as dizziness, chest tightness and shortness of breath;
Oxygen can be inhaled appropriately.
How to correctly select the oxygen concentration, flow rate, etc.?
If the oxygen inhaler at home can adjust the oxygen concentration, the low concentration of oxygen should be selected, that is, the oxygen concentration is less than 30%;
If the oxygen inhaler can adjust the flow rate, a low flow oxygen inhalation should be selected, that is, the oxygen suction flow rate is 1L/min - 3L/min.
Note: The oxygen inhalation time should not be too long, each oxygen inhalation can not exceed half an hour, if necessary, in the morning and afternoon each inhalation of oxygen, should not be excessive oxygen inhalation.
Is home oxygen necessary?
I believe that many pregnant mothers in the third trimester have had such an experience:
In the hospital to do fetal heart rate monitoring is not passed, the doctor let the pregnant woman inhale oxygen, and then do fetal heart rate monitoring, the result is normal.
Under the intervention of doctors, timely oxygen inhalation is necessary and very effective in improving fetal blood oxygen supply.
Therefore, pregnant mothers can also take oxygen at home, but it is not necessary.
Are there any side effects of oxygen inhalation?
Pregnant mothers have no side effects on the fetus when they inhale oxygen properly, but excessive oxygen inhalation, such as high oxygen concentration and flow, prolonged oxygen inhalation time, and large oxygen frequency, are all excessive oxygen inhalation.
Excessive oxygen inhalation may cause oxygen poisoning, produce harmful substances to the human body, cause abnormal metabolic functions of the body, and damage the health of mothers and babies.
How to monitor the fetus at home for hypoxia
For high-risk pregnant women:
For example, when the pregnant mother suffers from pregnancy hypertension, gestational diabetes, severe anemia, or the fetus has umbilical cord torsion, umbilical cord true knots and other abnormalities. Fetuses are more prone to acute and chronic hypoxia, and pregnant mothers should pay attention to home monitoring.
Number of fetal movements:
When the fetus is hypoxic in the womb, the most intuitive feeling of pregnant mothers is abnormal fetal movement.
In the early stage of hypoxia, fetal movement is abnormally frequent, and if there is no timely intervention, when severe hypoxia occurs, fetal movement is abnormally reduced.
Pregnant mothers feel that the fetal movement is abnormal, you can inhale oxygen for half an hour, continue to observe the fetal movement, if the fetal movement is still abnormal, then go directly to the hospital for fetal heart rate monitoring.
Home fetal heart rate monitoring:
Many pregnant mothers do not feel the fetal movement obviously, or will not count the fetal movements, then you can choose a home fetal heart rate monitor.
Through the fetal heart rate monitoring curve, it can be seen whether the baby has intrauterine hypoxia.
When a fetal heart rate monitoring is not passed, timely retesting, retest is still not passed, pregnant mothers can inhale oxygen for half an hour after the test, if the fetal heart rate monitoring after oxygen is still not passed, do not repeatedly inhale oxygen at home, go to the hospital in time to check it out.
Dr. Huang also stressed one point: oxygen inhalation is not a panacea. When after inhalation, fetal movement and fetal heart rate monitoring still indicate fetal hypoxia, you should go to the hospital for examination in time, and do not stubbornly think that relying on oxygen can solve the problem.
Because if the baby is hypoxic due to umbilical cord twisting, real knots in the umbilical cord, or the pregnant mother has placental abruption, etc. Oxygen inhalation can only alleviate for a while, can not solve the fundamental problem, but also needs further intervention and treatment.
