Pregnant women experiencing hypoxia may exhibit symptoms such as panic, chest tightness, breath-holding, difficulty breathing, and frequent and then decreased fetal movements. Whether pregnant or non-pregnant, patients with hypoxia will show symptoms such as panic, chest tightness and breath holding. Symptoms of hypoxia are more pronounced in pregnant women due to the gradual enlargement of the abdomen. When hypoxia is severe in pregnant women, dyspnea, cyanosis of the lips and limb endings may also occur. Hypoxia also affects the fetus in the womb, leading to hypoxia in the uterus and causing abnormal fetal movements. In the early stages of hypoxia, fetal movements will be too frequent, if not corrected in time, fetal movements will be significantly reduced. Fetal heart rate will also change accordingly. If the fetus has intrauterine ischemia and hypoxia, the fetal heart rate will be lower than 110 beats per minute or exceed 160 beats per minute. If a pregnant woman is deprived of oxygen for too long, it will affect the brain development of the fetus. Therefore, pregnant women should strengthen self-health management and fetal movement monitoring in their daily life, and seek immediate medical attention once abnormalities are detected.
