The fetus develops and grows in the mother's stomach and is pregnant in October. The growth of the fetus is closely related to the mother's daily life. In order to make the fetus in the womb grow better, mothers often eat some nutrients, exercise more and give the fetus early education. When the mother is sleeping, because she can't change the sleeping posture of the fetus, what is the normal range of fetal heart rate when pregnant women sleep at night?

What is the normal range of fetal heart rate when pregnant women sleep at night? When they were pregnant for about a month, the fetal heart began to beat. It was slow at first, only sixty or seventy times a minute. At this time, the heartbeat is very weak. During B-ultrasound examination, the fetal heartbeat can be displayed on the fluorescent screen of B-ultrasound. By the eighth week of pregnancy, the fetal heart rate can reach about 180 beats per minute. After 14 weeks of pregnancy, the fetal heart rate dropped to about 140 beats per minute, and then kept at 120~ 160 beats per minute. Doctors can not only listen to fetal heart directly with stethoscope, but also measure fetal heart sound with Doppler fetal heart detector. If the fetal heart rate is too fast, too slow or irregular in the third trimester, it means that the fetus is hypoxic in the uterus and needs to be treated in time. Suggestion: First of all, besides monitoring, you should get into the habit of counting fetal movements regularly every day. Now you should know the baby's schedule better. After pregnancy, the fetus continues to grow and develop in the mother. In order to meet and adapt to the needs of the fetus, the physiological function and anatomical structure of pregnant women will undergo some changes. In particular, the uterus gradually increases, and the blood flow of the uterus also increases greatly. Before labor, the whole abdomen is almost occupied by the uterus, which will inevitably push or squeeze the heart, lungs and urinary organs to varying degrees. If pregnant women sleep in supine position at this time, the enlarged uterus is pressed on the aorta behind the uterus, and the blood supply of the uterus is obviously reduced, which directly affects the nutrition and development of the fetus. If pregnant women have pregnancy poisoning, sleeping in supine position will affect the blood supply to the kidneys. If the flow rate is significantly reduced, the urine volume will also be reduced. The sodium salt in pregnant women and toxic substances produced in the metabolic process can not be discharged in time, which will aggravate the condition of pregnancy poisoning, lead to increased blood pressure, proteinuria, edema of lower limbs and vulva, and even convulsion and coma, which is medically called "eclampsia". Improper treatment will threaten the life safety of mother and baby.

If pregnant women lack calcium, they can't meet the needs of fetal growth and development. At this time, the calcium and phosphorus in pregnant women's bones and teeth can only be used to improve the blood calcium level to meet the needs of the fetus. If pregnant women can't timely and fully supplement calcium and vitamin D, then symptoms such as calf cramps, postpartum osteomalacia and loose teeth may occur.
