The fetal heart monitor chart determines that the child is hypoxic based on the baseline rate of the fetal heart, and observation of any deceleration of the fetal heart. There are two lines on the graph, one is the baseline fetal heart rate and the other is the baseline contractions. Fetal heart monitor charts are graphs that go through the recordings of fetal heart rate for more than 20 minutes. The normal baseline fetal heart rate is 110-160 BPM, and if it is not in this range, the fetal heart rate is abnormal. In addition, fetal heart rate deceleration after contractions is considered to be variant deceleration or late deceleration, which suggests the possibility of intrauterine hypoxia in the fetus. Don’t panic and keep a good attitude during pregnancy. Do your labor and delivery checkups on time to check the development of the fetus in all aspects. The specific situation, you need to follow the doctor’s advice to diagnose. If hypoxia occurs, you need timely oxygen and other treatments.
