A fetal Doppler ultrasound is a specialized diagnostic procedure used during pregnancy to evaluate the health and well-being of the fetus. The main purposes of a fetal Doppler ultrasound include:
1. Measuring Fetal Heart Rate
- Assessment: It measures the fetal heart rate and rhythm, ensuring that it is within the normal range.
- Early Detection: Helps in the early detection of potential heart-related issues in the fetus.
2. Monitoring Blood Flow
- Umbilical Artery: Assesses blood flow in the umbilical artery, which indicates how well the placenta is delivering nutrients and oxygen to the fetus.
- Other Vessels: Evaluate blood flow in other fetal vessels, such as the middle cerebral artery and ductus venosus, to detect circulatory problems.
3. Detecting Fetal Distress
- Health Monitoring: Provides information on fetal distress or hypoxia (low oxygen levels), allowing for timely medical interventions.
- High-Risk Pregnancies: Particularly useful in monitoring high-risk pregnancies, such as those with maternal hypertension, diabetes, or preeclampsia.
4. Evaluating Placental Function
- Placental Health: Assesses the function and health of the placenta, crucial for the fetus’s growth and development.
- Placental Insufficiency: Identifies issues like placental insufficiency, where the placenta fails to deliver adequate nutrients and oxygen.
5. Guiding Clinical Decisions
- Treatment Plans: Helps guide clinical decisions and treatment plans for both the mother and the fetus.
- Timing of Delivery: Assists in determining the timing and method of delivery in cases of fetal compromise.
