Oxygen deprivation during pregnancy can have certain effects on the fetus, and in severe cases, it can cause ischemic-hypoxic encephalopathy, which can lead to mental retardation or unresponsiveness and mental retardation in the baby after birth. In severe cases, it may also lead to cerebral palsy caused by ischemic-hypoxic encephalopathy, resulting in limb disorders, the degree of which is related to the degree of hypoxia. In severe cases, hypoxia may also lead to intrauterine distress, resulting in the possibility of stillbirth. The symptoms of hypoxia should be treated promptly and symptomatically. In general, if the fetus is hypoxic, it will have bradycardia or tachycardia. Under normal circumstances, the fetal heart rate should be 120-160 beats per minute. If it is not within this range, it means that the fetus has intrauterine hypoxia and should be given oxygen in time to improve the symptoms.
