How would you categorize an FHR tracing with a baseline of 110 BPM, moderate variability, and no accelerations or decelerations?

How would you categorize an FHR tracing with a baseline of 110 BPM, moderate variability, and no accelerations or decelerations?

• A. Category I FHR pattern
• B. Category II FHR pattern due to bradycardia
• C. Category II FHR pattern due to absent accelerations
• D. Category II FHR pattern due to bradycardia, absent accelerations

Answer: (C)

The FHR tracing described has a baseline heart rate of 110 beats per minute (BPM), which is classified as bradycardia since the normal range for fetal heart rate is typically between 120 and 160 BPM. The presence of moderate variability indicates that there is a normal, healthy degree of fluctuation in the heart rate, which typically suggests a well-oxygenated and healthy fetus. However, the absence of both accelerations—indicative of fetal activity or a response to stimuli—and decelerations—indicating stress or potential issues—further categorizes the tracing. Category II patterns indicate that there are some atypical features that could require further monitoring or evaluation. The lack of accelerations is particularly significant because it can indicate an absence of fetal movement or response to external stimuli, which may raise concerns, especially when combined with a bradycardic baseline. Thus, the FHR tracing is not a straightforward normal (Category I) or high-risk (Category III) pattern but rather falls into Category II due to the absence of accelerations. This justifies the answer as appropriate given the criteria for categorization, focusing on the specific elements of the tracing that position it within the spectrum of surveillance needed.
