The monitor manufacturer of fetal monitor is more and more widely used, and play an important role in the obstetric hospital. So how can the fetal monitor play the biggest effect, should as far as possible to extend the monitoring time. Exactly speaking, only to do the whole process monitoring, to ensure the abnormal situation will not be missed. Only in a certain stage of the production process for a short period of monitoring, it can not be said that there is no threat to the occurrence of fetal abnormalities. You can use this word, the fetus in the world to Master to experience a hard journey. First of all, every contraction, to accept a fetal hypoxia test. In the progress of labor, uterine gradually strengthen, fetal reserve may gradually reduce. Some can survive without fetal abnormalities in the first stage of labor, and the second stage of labor is not necessarily abnormal. In the first stage of labor of a certain period of time, care as the representative, is only interpret out of context. Not only are the changes in the intensity of uterine contraction, length of labor and maternal consumption of all the fetus play a role, especially abnormal umbilical cord of fetal threat is more significance. Changes in body position can be at any time to the umbilical cord, after the rupture of the amniotic fluid and fetal decline is almost no exception to the umbilical cord has an impact, but only slightly different. If the umbilical cord around the neck caused by the relatively short umbilical cord, in a short time the umbilical cord can be tightened at the same time and being oppressed.

Because there is no stimulation during pregnancy do (NST) is in the absence of contractions. When you go into labor (regular contractions) still can make nothing of it. Especially because the fetus in the birth canal for a few hours, which said the journey is distant, hardships, who will not be able to conclude that no accident, not to mention the hospital sooner or later, delivery conditions, midwife or surgical operation of differences. Therefore, the newborn is good or not, can not be compared with the results of NST, because the relationship between the two is too long, almost can be said to be the two century.
