Fetal monitoring, clinically known as fetal heart rate monitoring, is usually performed for a single 20-minute session, which can be extended for another 20 minutes if the results are unsatisfactory. Fetal heart rate monitoring during labor and the use of oxytocin to induce labor is extended accordingly. Fetal heart rate monitoring is a common test during pregnancy and labor. Fetal heart monitoring during pregnancy is one of the means of observation in case of abnormal fetal movement or fetal heartbeat. Fetal heart monitoring precautions: 1, during normal prenatal checkups, people without high-risk factors should have fetal heart monitoring once a week starting from the 36th week of pregnancy; 2, people with high-risk factors can be advanced to around the 32nd week of pregnancy; 3, pregnant women in the late stages of pregnancy should have fetal heart monitoring when there is premature rupture of fetal membranes, abnormal vaginal bleeding, preterm labor, abnormal fetal movement, etc.; 4, the fetal heart monitoring in labor and delivery can be used to know whether the baby is hypoxic or not, and also to observe fetal heart movement and abnormality. Fetal heart rate monitoring during labor can not only know whether the fetus is hypoxic or not, but also can be used to observe the contraction situation and the effect of contraction on the fetal heart rate, which can provide a guarantee and basis for the safety of labor and the change of the delivery method (e.g., switching from normal labor to cesarean section).
