When does a pregnant woman need to be hospitalized for delivery? (Picture source: Data map) During pregnancy, pregnant women and their families really need to be more vigilant and do a good job of self-monitoring. The safe self-monitoring of the fetus in utero can be completed by counting fetal movements, that is, the number of fetal movements in one hour each in the morning, noon, and evening, multiplied by 4, is 12 hours of fetal movement. If the fetal movement exceeds 30 times within 12 hours and the fetal movement exceeds 5 times per hour, it indicates that the fetus is in good condition. If the fetal movements are less than 20 times in 12 hours and less than 3 times per hour, the fetus may be hypoxic.
