Fetal heart baseline
It is normal that the fetal heart base line is between 120 beats/min and 160 beats/min. If it is lower than 120 times/min or higher than 160 times/min, there may be an abnormal situation. At this point, we need doctors to make medical judgments according to the physical condition of expectant mothers.
Fetal heart rate swing amplitude
The normal range should be 10-25bpm. If the swing amplitude is too large or too small, it may indicate that the fetal venous circulation is blocked and it is necessary to seek the help of a doctor in time. At the same time, pay attention to whether the oscillation frequency is greater than or equal to 6( 1 minute fluctuations). If the baseline fluctuation has frequency, it means that the fetus is in good health.
Fetal movement
Observe the rising of fetal movement, the change time of fetal heart rate and the number of fetal movements. If the fetal heart rate can temporarily increase above 15bpm after uterine contraction, it means that the fetus is in good health. The change time of fetal heart rate is also an important index to judge fetal health; At the same time, in the fetal heart monitoring time of about 20 minutes, the number of fetal movements is more than 3 times. If it is less than 10 times every 12 hours, it may indicate that the fetus is hypoxic.
Systolic pressure waveform diagram
Normal uterine contraction pressure is about 20mmHg. If the uterine contraction pressure exceeds 50 times for three consecutive times in 10 minutes, it may indicate that labor is about to begin.
Correct interpretation of fetal heart monitoring chart
Mothers-to-be should learn to correctly interpret the fetal heart monitoring chart so as to better understand the health status of the fetus. At the same time, if you find anything unusual, you should seek the help of a doctor in time.
