Fetal heart rate monitoring is the abbreviation for fetal heart rate fetal diagram. It is a graph that records the fetal heart rate curve and the contraction pressure waveform for clinical analysis using a fetal heart rate electronic monitor. It is the main test to correctly assess the status of intrauterine fetal conditions. Means. Using microwave technology, no harm to children, only need to buy a fetal heart rate detector. Especially after 4 years of pregnancy, it is important for baby care. Interesting things can sometimes hear baby snoring. Fetal heart rate monitoring is mainly two lines, the upper one is the fetal heart rate, under normal circumstances fluctuations between 120-160, the general performance of the underlying heart rate line performance as a waveform straight line, appear fetal movement heart rate will rise, there is an upward The protuberance curve gradually declines after the fetal movement is completed. The fetal movement count is >30/24 hours as normal, and <10 times every 12 hours suggests fetal hypoxia. The following one shows intrauterine pressure, as long as the child shrinks, it will increase, then will maintain about 20mmHg.
