What is the normal range of the fetal heart rate during pregnancy?

The normal range of the fetal heart rate during pregnancy is typically between 120 to 160 beats per minute. This range is established based on numerous studies that have monitored fetal heart activity throughout gestation. Within this range, a fetal heart rate indicates that the fetus is responding appropriately to its environment and receiving adequate oxygenation.

Fetal heart rates lower than 120 beats per minute could suggest potential issues, such as fetal distress, especially if this is sustained. Conversely, rates above 160 beats per minute may indicate tachycardia, which can also be a concern depending on the clinical context. Understanding this normal range is crucial for healthcare professionals in assessing fetal well-being during prenatal care.
