What category is assigned to tracing with absent variability without decelerations?

Tracing with absent variability and no decelerations is classified as Category 2 in the fetal heart rate (FHR) classification system. This category is characterized by a tracing that does not meet the criteria for Category 1, which includes the presence of normal baseline variability and the absence of concerning decelerations. Category 2 is a "compromised" category, indicating some degree of abnormality in the fetal heart rate pattern but not severe enough to classify as Category 3, which reflects more significant abnormalities such as recurrent late decelerations, absent variability with decelerations, or signs of fetal distress. Category 2 suggests monitoring is required, and further evaluation of the fetal condition is necessary, while allowing more time for an appropriate clinical intervention.
