Which FHR category indicates the need for further evaluation and surveillance?

Category II Fetal Heart Rate (FHR) patterns are characterized by a mix of normal and abnormal features, which do not fit neatly into the well-defined normal patterns of Category I or the concerning patterns of Category III. This category indicates that the fetal heart rate shows signs that are neither consistently normal nor consistently abnormal. As such, it warrants further evaluation and continuous surveillance to assess the fetal status, determine the cause of the variability, and decide on appropriate interventions if necessary. Monitoring and analyzing these patterns can provide valuable insights that help guide clinical decisions regarding the care of both the fetus and the laboring mother.

In contrast, Category I patterns are reassuring and are considered normal, while Category III patterns are associated with more severe anomalies that require immediate interventions. Thus, the distinction is crucial in determining the appropriate clinical response.
