Pregnancy at 30 Weeks: Understanding the Vital Signs and Precautions

Pregnancy at 30 weeks marks the mid-to-late stage, during which it is crucial to be aware of the various developmental indicators of the fetus. These indicators can be obtained through ultrasound examination, commonly known as a B-scan. For most pregnant women, understanding the standard data is essential as it allows them to compare their own results and assess the fetus's development. So, what are the standard B-scan data for pregnancy at 30 weeks? Let's take a look.

1. Standard B-scan Data for Pregnancy at 30 Weeks

a. The average biparietal diameter (BPD) at 30 weeks is 7.83 ± 0.62 cm, and the average femur length is 5.77 ± 0.47 cm. If the femur length is shorter than average, it is recommended to strengthen nutrition intake, consume more high-quality protein, monitor regularly, and attend prenatal checkups.

b. The normal heart rate of the fetus is between 120 and 160 beats per minute.

c. The normal amniotic fluid depth is between 3 and 7 cm.

2. Precautions for Pregnancy at 30 Weeks

a. Ensuring Nutritional Needs: The nutritional demands of the fetus peak during this stage as its bones and muscles continue to mature. It is crucial to consume adequate amounts of protein, vitamin C, iron, and calcium. Foods like milk, lean meat, and various vegetables are recommended. Sesame seeds are rich in iron and can be eaten roasted or added to dishes. Additionally, it is important to take any prescribed nutritional supplements as directed by your doctor.

b. Regular Prenatal Checkups: As the delivery date approaches, the frequency of prenatal checkups increases. It is recommended to have checkups every two weeks during this period, as they are crucial for monitoring the fetus's health and preparation for delivery. If there are any concerns about the fetal position, your doctor can advise on ways to correct it. Prenatal checkups are also vital for preventing preterm birth and preeclampsia.

3. Examination Items for Pregnancy at 30 Weeks

a. Routine Prenatal Checkups: At 30 weeks, you will undergo your sixth prenatal checkup. Routine checkups typically include measurements of blood pressure, weight, uterine height, abdominal circumference, fetal heart rate, blood routine, and urine routine. These measurements provide a comprehensive overview of your condition and help doctors assess the fetus's development. It is also recommended to keep track of fetal movements daily.

b. Key Prenatal Examination Items: The necessity of urine routine tests: Through the analysis of urine appearance and composition, urine routine tests can detect potential urinary system diseases or diabetes in pregnant women.
