If the fetal heart rate, fetal position, size and pelvis of the pregnant woman are suitable, the delivery can be normal, but if there are signs of fetal hypoxia and poor heart rate during the delivery, it will be necessary to turn to cesarean section. Whether or not the labor can be normal needs to monitor the fetal heart rate, fetal size, fetal position, maternal pelvis and fetal head articulation, as well as the overall physical condition of the pregnant woman and other comprehensive considerations. Amniotic fluid protects fetal movement in the uterus, makes it less likely that the fetus or umbilical cord will be directly squeezed during uterine contractions in labor, and lubricates the birth canal. However, the amount of amniotic fluid is not the main factor in determining whether a labor is suitable for normal delivery, it is only a reference factor. Even if the amniotic fluid is low, as long as the fetal heart rate, fetal position, size and the pregnant woman’s pelvis are suitable, a normal delivery is still an option. However, the heart rate of the fetus needs to be closely monitored during labor, and if fetal hypoxia is detected, cesarean section is needed immediately.
