The fetal heart monitor has a lot of broken wires, consider that the fetal movement is too frequent, or the fetal heart monitor strap is too loose, the fetal movement occurs when the probe shift contact is not good, it is recommended that the pregnant woman change position monitoring, take the side lying position monitoring, the strap will be tied tighter, in the fetal movement is frequent when the probe shift is not easy to occur. The fetal heart monitoring can find out the fetal reserve condition in the uterus and whether there are contractions, it is easy to pass the fetal heart monitoring after pregnant women eat, pregnant women can bring small snacks, etc. If there is no fetal movement and the monitoring does not pass, pregnant women can eat chocolate or milk, soybean juice, etc. to induce fetal movement to help pass the fetal heart monitoring.
