What is the normal variation in fetal heart rate (FHR)?

In assessing the normal variation in fetal heart rate (FHR), a typical range is recognized as 5 to 15 beats per minute (BPM). This range indicates the degree of fluctuation in the fetal heart rate that occurs due to the autonomic nervous system's regulation in response to various stimuli. Variability is crucial as it reflects fetal oxygenation and well-being; adequate variability is often a sign that the fetus is healthy and that there are no signs of distress.

The normal variation is an important indicator for healthcare providers during labor and delivery, helping them assess fetal health through continuous monitoring. Variability that falls within the established range is associated with strong fetal neurodevelopment and a well-functioning autonomic nervous system, which is essential for fetal health.

Assessing variability is a standard practice in intrapartum care, making the understanding of this specific range critical for midwives and other healthcare practitioners involved in labor and birth.
