How to monitor the heart rate of the fetus

Pregnant pregnant women always have a lot of viewing items to ensure the safety and health during pregnancy. The effect of fetal heart rate monitoring is to let pregnant women know the development of the fetus. What is the effect of fetal heart rate monitor?

First, the effect of fetal heart rate monitor

Fetal heart rate monitoring is the fetal heart rate of fetal constriction, is the use of fetal heart rate electronic monitor to the fetal heart rate curve and uterine pressure waveform down for clinical analysis of the graphics, is an accurate assessment of the situation within the fetus of the primary view Tactics. Use microwave skills, no harm to the child, just need to buy fetal heart view can be. Especially 12 weeks of pregnancy in the future, since the baby is very important to guard. Funny things sometimes hear baby hiccups. Fetal heart rate monitoring is the first two lines, the above is a fetal heart rate, under normal circumstances shake between 120-160, usually the performance of the basic heart rate line for a straight line, showing fetal heart rate will rise, showing an upward Protruding curve, fetal movement will gradually decline after the completion of fetal movement count> 30 times / 12 hours for the normal, <10 times every 12 hours prompted fetal hypoxia. The following one shows intrauterine pressure, as long as the sub-shrink will increase, then will adhere to about 20mmHg. Fetal heart monitoring is the content of fetal heart rate monitoring fetal heart rate by the sympathetic nerve and parasympathetic regulation, after the signal traces of fetal heart changes in the formation of the monitoring curve of the curve, to understand the fetal movement, the contractions when the fetal heart to respond to Estimation of intrauterine fetuses with or without hypoxia. Normal pregnancy from the beginning of 37 weeks of pregnancy to do a weekly fetal heart rate monitoring, if complications or complications, from the first 28 to 30 weeks of pregnancy to do. Should pay attention to the rhythm of fetal heart sound is not suddenly Huzuo slow, etc., normal fetal heart sounds 120 to 160 times / min, if the fetal heart rate of 160 times / min or more or 100 times / min have shown fetal intrauterine hypoxia, Should be treated in time.

Second, the fetal heart rate monitor to do the factors of contractions

There are several factors that measure the contractions of the monitor manufacturers. First, in this gestational week, you may have contractions, and perhaps not. If so, that might be Brackston? Hicks shortened (also called "fake contractions"), usually less painful, no rules, nor frequent. This contusion is not bad, but also very common in the third trimester. If you have not been pregnant to 37 weeks to show a continuation, repeated and regular contractions, may be traces of premature birth, the doctor may give you speculation test, such as doing B-see the cervix is not already open , And then check the vaginal secretions in the fetal fibronectin, if it is positive to explain the onset of premature birth within 2 weeks may be great.

Another factor in monitoring contractions is to see if you have contraction period, fetal heart rate is not a change of attack. The contractions stress test will usually check this. If the baby's fetal heart rate in the contraction period slowed down, it may indicate that your placental condition is bad, the fetus's oxygen supply is difficult.
