What category is assigned to tracing with absent variability with decelerations?

Tracing with absent variability combined with decelerations is classified as Category 3. This category is characterized by abnormal fetal heart rate patterns, which include sinusoidal patterns and those with absent variability in conjunction with recurrent late decelerations or variable decelerations. The presence of absent variability indicates that the fetal heart is not responding adequately to stimuli, suggesting potential fetal distress or compromised well-being.

In clinical practice, these patterns prompt immediate evaluation and intervention because they are indicative of a significant risk for adverse outcomes. Therefore, assigning Category 3 reflects the seriousness of the situation and necessitates close monitoring and potential medical intervention to ensure the safety of the fetus.
