Fetal movement and fetal heart sounds

\"Shiyue pregnant, give birth to a child\". In long long of during pregnancy in, fetal not only in uterine within sucking with various nutrition, also in kept to to maternal issued own growth of signal, this is FM and fetal heart sound to reflect out fetal growth and health of situation, measuring listen to FM and fetal heart sound to reflect out fetal growth and health of situation, measuring listen to FM and fetal heart sound is prenatal check of important project, once found FM does not law or fetal heart sound weak, on should immediately take necessary of rescue measures, case fetal occurs case.
　
First fetal movement. As long as the function of the placenta, the processing of sending sufficient oxygen, fetal growth and development of sound, the small life there will be intermittent activities freely within the uterus, which is. General at the time of 16 weeks of gestation, the receiver can hear the fetal movements, 18-20 weeks of pregnancy, you are also able to feel fetal movement. Clinical statistics show that fetal movement of approximately 3-5 per hour, not be less than 10 times within 12 hours. Usually longer more fetal movements active during pregnancy. But in the period of pregnancy is not, because of the fetal head down to maternal pelvis position, hence number of fetal movement is often reduced, this is a normal phenomenon. Under normal circumstances, if fewer fetal movements, it indicates that the decline in quality of life of the fetus. Gradually reduced fetal movement is often severe asphyxia of fetus alert, this to give a high degree of attention to pregnant women and their families.
　
Fetal Heart sounds. Place the handset on the abdominal wall to the appropriate location, you can hear the fetal heartbeat sound, this is the fetal heart sound. Fetal Heart sounds like a pillow watch ticking, have certain rules, under normal circumstances, pregnancy at 20 weeks to hear the fetal heart sound measurement, it later than the emergence of fetal movement, normal fetal heart rate fast and strong, 120-160 beats per minute, medium-term pregnancy, fetal heart rate can reach more than 160 beats per minute. Antenatal examination, fetal heart sound is an indispensable item through this screening. Can judge the growth and health of the fetus, when fetal heart rate suddenly go faster or slower, that is, when there were irregular situations, we should pay our attention to. Pregnant women and their families at home to audiometry fetal heart sound, not the receiver as well as by the ear to the families in the number of pregnant women on the abdominal wall of fetal heart, when fetal position properly after 24 weeks of pregnancy, fetal heart sound in the correct location is the umbilical cord is central or left and right sides of the umbilical.
　
Listen to fetal heart sound although no what special of skills, General people are can master, but must and abdominal within of several noise accurate area separate, for example uterine noise (is blood flow by issued of sound), this is and pulse frequency same of hair dryer sample noise, General people are can master, but must and pregnant women abdominal within of several noise accurate area separate, for example Palace noise (is blood flow by issued of sound), this is and pulse frequency same of hair dryer sample noise, General in abdominal in side more obvious; and as abdominal active pulse tone (is abdominal active pulse of beat sound), its rate and of pulse consistent; also has front mentioned of FM tone, is fetal limb collision uterine wall issued of sound, it is a no rhythm of noise and so on. Once suspected fetal heart does not normal Shi, should timely to hospital do further auscultation, modern medical can using multiple means, as extraction pregnant women uterine within amniotic fluid, and laboratory 24 hours within of urine, and test notes in the placenta health milk pigment of accountants, and by fetal heart guardianship instrument, and fetal ultrasonic, various instrument, to check and diagnosis fetal growth and survival of situation, to in appears problem Shi, timely take corresponding of protection and the Save measures.
