If the FHR variability is within a range of 6-25 bpm, what is this classified as?

When fetal heart rate (FHR) variability is classified as moderate, it reflects a range of 6 to 25 beats per minute (bpm). This level of variability is considered normal and indicates that the fetus is likely responding well to the surrounding environment, including the influence of the autonomic nervous system. Moderate variability is a reassuring sign, as it suggests good oxygenation and well-being of the fetus, and it is often associated with healthy fetal heart maintenance.

In contrast, minimal variability is identified when the fluctuation in FHR is less than 5 bpm. Marked variability refers to fluctuations that exceed 25 bpm, which might warrant further investigation depending on the clinical context. Absent variability indicates that there is no detectable change in FHR, which can be concerning and may suggest compromising conditions for the fetus. Recognizing and interpreting moderate variability is crucial for fetal monitoring, as it plays a significant role in assessing fetal health during labor and delivery.
