The fetal heart monitor is not accelerated enough, that is, when the fetal heart monitor, suggesting that the fetal heart is not accelerated enough, usually because the fetus is not obvious fetal movement, may be the fetus itself is in a sleep state, may also be related to the physical condition of the pregnant woman, the following common situations. 1, the fetus is resting: when the fetus is in a sleep or rest state, the fetal heart monitor will suggest that the heart rate is slow, and there is no obvious acceleration, it is recommended that the pregnant woman appropriate walking activities, or stroking the abdomen to wake up the fetus. or stroking the abdomen to wake up the fetus, and then check again after the fetal movement is obvious; 2, low blood sugar of pregnant women: if pregnant women fast or feel hungry due to other examinations, the fetus may not have obvious activity due to low blood sugar, so you can supplement some food appropriately, such as bread, milk, cookies, etc., and then test again after half an hour; 3, intrauterine hypoxia: if the fetus is in a state of hypoxia in the uterine cavity, it will also make the heart rate of fetal monitoring low, acceleration If the fetus is in intrauterine hypoxia, the fetal heart rate will be low, the acceleration will be insufficient, and the fetal movement will not be obvious. If the fetal heart monitoring index is always not pass, even the heart rate is getting slower and slower, and the fetal movement is obviously very little, it may be related to fetal growth retardation, malformation, intrauterine infection and other abnormalities, and fetal ultrasound or other related examinations are needed to clarify the specific causes and intervene to ensure the health of the fetus and the pregnant woman.
