At 24 weeks of pregnancy, umbilical artery ri: 0.67, s/d 3.0

Patient's question:

No

Doctor's answer:

This value is normal, don't worry. A normal S/D value should be less than 3. If it's higher than 3, there may be a risk of fetal hypoxia. It is recommended that you undergo another prenatal check-up at 28 weeks of pregnancy, regularly monitor fetal heart rate, and pay attention to fetal movement. If there are any abnormal fetal movements, seek medical attention promptly.
